INTEGRATED CIRCUITS 74ABT16373B 74ABTH16373B 16-bit transparent latch (3-State) Product specification Supersedes data of 1995 Aug 03 IC23 Data Handbook 1998 Feb 27 Philips Semiconductors Philips Semiconductors Product specification 16-bit transparent latch (3-State) 74ABT16373B 74ABTH16373B FEATURES • 16-bit transparent latch • Multiple VCC and GND pins minimize switching noise • Power-up 3-State • Live insertion/extraction permitted • Power-up reset • 3-State output buffers • 74ABTH16373B incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs When nOE is Low, the latched or transparent data appears at the outputs. When nOE is High, the outputs are in the High-impedance “OFF” state, which means they will ne [ ... ]
