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 be open, when not used.
TTL level input
Wide operating temperature range
Ta = –40 to + 85°C
