74ABT16373BDGG,112

Overview

The NXP USA Inc. 74ABT16373BDGG,112 is a high-performance BiCMOS 16-bit transparent latch featuring dual octal sections with independent control and 3-State output buffers. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40 °C to +85 °C. The device provides an output capability of +64 mA/-32 mA and includes power-up 3-State functionality. Propagation delays are typically 2.5 ns (Dn to Qn) and 2.1 ns (E to Qx). It utilizes a TSSOP48 package.

Feature Summary

• Dual octal transparent latches coupled to two sets of eight 3-State output buffers for bus-oriented applications
• Power-up 3-State outputs and live insertion/extraction permitted for non-destructive hot insertion
• Multiple VCC and GND pins designed to minimize switching noise during operation

Applications

• Bus oriented applications requiring byte-controlled data storage
• Driving heavily loaded 3-State buses
• Interfacing with MOS memories or MOS microprocessors

Procurement Notes

Verify the specific BDGG suffix corresponds to the TSSOP48 plastic thin shrink small outline package (SOT362-1) with a 6.1 mm body width. Confirm that the component status aligns with current availability as Philips Semiconductors reserves the right to make changes. Ensure compatibility with the specified 4.5 V to 5.5 V supply voltage range and -40 °C to +85 °C operating temperature limits before integration.

Selection Notes

Select this component when designing systems requiring high-speed data latching with significant drive capabilities. The ABT series offers low static and dynamic power dissipation combined with high speed. Consider the separate control logic for each byte and the independent Output Enable inputs. The multiple VCC and GND pins are critical for managing noise in dense circuit designs compared to standard single-supply configurations.

Part Context

This part belongs to the 74ABT logic family, which combines BiCMOS technology for high performance. It replaces earlier versions such as the 74ABT16373B/74ABTH16373B. The device functions as a dual octal transparent latch, distinct from flip-flops by its transparency when the Latch Enable input is HIGH. It is manufactured under the Philips Semiconductors brand, now NXP USA Inc.
