Overview
HD74BC573A Octal D Type Transparent Latches With 3 State Outputs ADE-205-021A (Z) Rev.
1 March 1993 Description The HD74BC573A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process.
The device features low power dissipation that is about 1/5 of high speed bipolar logic IC, when the frequency is 10 MHz.
The device has eight D type latches with three state outputs in a 20 pin package.
When the latch enable input is high, the Q outputs will follow the D inputs.
When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again.
When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
Features • • • • Input/Output are at high impedance state when power supply is off.
Built in input pull up circuit can make input pins ...
