SN54ABT16373A, SN74ABT16373A are 16-bit transparent D-type latches with 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. These devices can be used as two 8-bit latches or one 16-bit latch. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. A buffered output-enable (OE) input can be used to place the eight outputs in either a n
The document describes the SN54ABT16373A and SN74ABT16373A, which are 16-bit transparent D-type latches with 3-state outputs. These devices utilize a state-of-the-art EPIC-II BiCMOS design to significantly reduce power dissipation while providing high-drive outputs capable of driving highly capacitive or low-impedance loads without interface components.
The datasheet provides comprehensive electrical characteristics, timing requirements, and switching specifications for both the military-grade SN54ABT16373A (operating from -55°C to 125°C) and the commercial-grade SN74ABT16373A (operating from -40°C to 85°C). It details package options including plastic shrink small-outline, thin shrink small-outline, and fine-pitch ceramic flat packages.

The device is characterized for operation from -40°C to 85°C.
Yes, a buffered output-enable (OE) input can place the eight outputs in either a normal logic state or a high-impedance state.
The device enters the high-impedance state during power up or power down.
