The 74ABT161543 and 74ABTH161543 are 16-bit latched transceivers with dual enable and master reset functions. They feature two sets of 8-bit octal transceivers with D-type latches for data storage in both directions. The product has multiple VCC and GND pins to minimize switching noise. It also has strong output capability, latch-up protection, and electrostatic discharge protection.
The Philips 74ABT161543 and 74ABTH161543 are high-performance BiCMOS devices designed as 16-bit latched transceivers. These components combine low static and dynamic power dissipation with high speed and high output drive capabilities. The 74ABT161543 model does not include the Bus hold feature, whereas the 74ABTH161543 incorporates Bus hold data inputs to eliminate the need for external pull-up resistors on unused inputs.
