The 74F521 is an expandable 8-bit comparator. It compares two words of up to eight bits each and provides a LOW output when the two words match bit for bit. The expansion input IA=B also serves as an active LOW enable input

The 74F533 consists of eight latches with 3-STATE outputs for   bus   organized   system   applications.   The   flip-flops appear transparent to the data when Latch Enable (LE) is HIGH.  When  LE  is  LOW,  the  data  that  meets  the  setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH the bus output is in the high impedance state.

The 74F541 except that the inputs and outputs are on opposite sides of the package (see Connection Diagrams). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density

This 8-bit flip-flop features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops of the SN74F574 are edge-triggered D-type flip-flops. On the positive transition of the clock (CLK) input, the Q outputs will be set to the logic levels that were set up at the data (D) inputs. A buffered output enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for interface or pullup components. The output enable (OE) does not affect the internal operations of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The SN74F574 is characterized for operation from 0?C to 70?C.

The F74 is a dual D-type flip-flop with Direct Clear and Set inputs  and  complementary  (Q,  Q)  outputs.  Information  at the input is transferred to the outputs on the positive edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. After the Clock Pulse input threshold  voltage  has  been  passed,  the  Data  input  is locked out and information present will not be transferred to the  outputs  until  the  next  rising  edge  of  the  Clock  Pulse input.
