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.

• Inputs and outputs on opposite sides of package allow easy interface with microprocessors
• Useful as input or output port for microprocessors
• Functionally identical to ABT373
• 3-STATE outputs for bus interfacing
• Output sink capability of 64 mA, source capability of 32 mA
• Guaranteed output skew
• Guaranteed multiple output switching specifications
• Output switching specified for both 50 pF and 250 pF loads
• Guaranteed simultaneous switching, noise level and dynamic threshold performance
• Guaranteed latchup protection
• High impedance glitch-free bus loading during entire power up and power down
• Nondestructive hot insertion capability
