74ABT16646 is a 16-bit bus transceiver/register (3-State) product produced by Philips. It has independent A and B bus registers, multiple VCC and GND pins, minimized switching noise, live insertion/extraction permitted, power-up 3-State, power-up reset, multiplexed real-time and stored data, outputs sink 64mA and source 32mA, latch-up protection exceeds 500mA per JEDEC Std 17, 74ABTH16646 incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs, ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model, and other features.
This document is a product specification datasheet for the Philips 74ABT16646 and 74ABTH16646, which are high-performance BiCMOS 16-bit bus transceiver/register devices. These components combine low static and dynamic power dissipation with high speed and high output drive capabilities.
| Output capacitance | 7 pF |
|---|---|
| Outputs sink current | 64mA |
