Octal D Type Transparent Latches With 3 State Outputs
ADE-205-040 (Z)
Rev. 0
June 1993
Description
HD74BC563A 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.
