Texas Instruments SN74HCS573/SN74HCS573-Q1 Octal D-Type Latch

Texas Instruments SN74HCS573/SN74HCS573-Q1 Octal Transparent D-Type Latch contains eight D-type latches. All inputs include Schmitt-trigger architecture. All channels share a latch enable (LE) input and output-enable (OE) input. The Texas Instruments SN74HCS573/SN74HCS573-Q1 has a flow-through pinout that allows easier bus routing.
