DM74LS573
Octal D-Type Latch with 3-STATE Outputs
General Description
The DM74LS573 is a high speed octal latch with buffered
common Latch Enable (LE) and buffered common Output
Enable (OE) inputs.
This device is functionally identical to the DM74LS373, but
has different pinouts.
Features
I
Inputs and outputs on opposite sides of package allow-
ing easy interface with microprocessors
I
Useful as input or output port for microprocessors
I
Functionally identical to DM74LS373
I
Input clamp diodes limit high speed termination effects
I
Fully TTL and CMOS compatible
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
