SN74ALS534A OCTAL D-TYPE EDGE-TRIGGERED FLIP-FLOP

These octal D-type edge-triggered flip-flops feature 3-state outputs designed specifically for driving highly capacitive or relatively lowimpedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. On the positive transition of the clock (CLK) input, the Q outputs are set to .

Features

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 interface or pullup components. 4Q GND CLK SN54ALS534A . . . J PACKAGE SN74ALS534A, SN74AS534 . . .
