Octal D-Type Latch with 3-STATE Outputs
General Description
The ABT573 is an octal latch with buffered common Latch
Enable (LE) and buffered common Output Enable (OE)
inputs.
This device is functionally identical to the ABT373 but has
broadside pinouts.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
