CD4538 Dual Precision Monostable Multivibrator IC DIP-16 Package
The CD4538 is a dual, precision monostable multivibrator with independent trigger and reset controls. The device is retriggerable and resettable, and the control inputs are internally latched. Two trigger inputs are provided to allow either rising or falling edge triggering. The reset inputs are active low and prevent triggering while active. Precise control of output pulse-width has been achieved using linear CMOS techniques. The pulse duration and accuracy are determined by external components RX and CX. The device does not allow the timing capacitor to discharge through the timing pin on power-down condition. For this reason, no external protection resistor is required in series with the timing pin. Input protection from static discharge is provided on all pins.

CD4543 BCD to 7 Segment Decoder IC DIP-16 Package
CD4543 is a BCD-to-seven segment latch/decoder/driver designed primarily for liquid-crystal display (LCD) applications. It is also capable of driving light emitting diode (LED), incandescent, gas-discharge, and fluorescent displays. This device is functionally similar to and serves as direct replacement for the CD4056 when pin 7 is connected to VSS. It differs from the CD4056B in that it has a display blanking capability instead of a level-shifting function and requires only one power supply. When the CD4056 is used in the level shifting mode, two power supplies are required. When the CD4543 is used for LCD applications, a square wave must be applied to the PHASE input and the backplane of the LCD device. For LED applications a logic 1 is required at the PHASE input for common-cathode devices; a logic 0 is required for common-anode devices (see truth table). The CD4543B is supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
CD74HC354 High Speed CMOS Logic 8-Input Multiplexer Register IC (74354 IC) DIP-20 Package
The CD54HC354, CD74HC354, and CD74HCT354 are data selectors/multiplexers that select one of eight sources. In both types, the data select bits S0, S1 and S2 are stored in transparent latches that are enabled by a low latch enable input, LE. In the HC/HCT354 the data enable input, E, controls transparent latches that pass data to the outputs when E is high and latches in new data when E is low. In both types the three-state outputs are controlled by three output-enable inputs OE1, OE2, and OE3.
CD74HC670 High Speed CMOS Logic 4-by-4 Register IC (74670 IC) DIP-16 Package
The ?HC670 and CD74HCT670 are 16-bit register files organized as 4 words x 4 bits each. Read and write address and enable inputs allow simultaneous writing into one location while reading another. Four data inputs are provided to store the 4-bit word. The write address inputs (WA0 and WA1) determine the location of the stored word in the register. When write enable (WE) is low the word is entered into the address location and it remains transparent to the data. The outputs will reflect the true form of the input data. When (WE) is high data and address inputs are inhibited. Data acquisition from the four registers is made possible by the read address inputs (RA1 and RA0). The addressed word appears at the output when the read enable (RE) is low. The output is in the high impedance state when the (RE) is high. Outputs can be tied together to increase the word capacity to 512 x 4 bits.
CH340C (SMD SOP-16 Package) USB to Serial TTL Converter IC
CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer or converting existing UART devices to USB interface.
