74ALVCH16373DGG:51

Overview

The 74ALVCH16373DGG:51 is a 16-bit D-type transparent latch manufactured by NXP Semiconductors, housed in a TSSOP48 package (SOT362-1). It features two independent 8-bit sections with separate Latch Enable (LE) and Output Enable (OE) controls. The device operates within a supply voltage range of 1.2 V to 3.6 V and complies with JEDEC standard JESD8-B. Key electrical characteristics include a propagation delay of 2.1 ns at 3.3 V, a maximum static current of 40 µA, and an output drive capability of ±24 mA at VCC = 3.0 V. It supports direct interface with TTL levels and includes bus hold inputs.

Feature Summary

• Incorporates bus hold data inputs to eliminate the need for external pull-up or pull-down resistors on unused lines.
• Features low inductance multiple VCC and GND pins designed to minimize noise and ground bounce during operation.
• Provides 3-state outputs suitable for bus-oriented applications with high-impedance OFF-state control.

Applications

• Bus-oriented applications requiring 16-bit data storage
• Mixed 3.3 V and 5 V logic environments
• Systems requiring direct interface with TTL levels

Procurement Notes

Verify the specific ordering suffix ':51' against manufacturer documentation to confirm reel packaging specifications. Confirm that the TSSOP48 package variant matches the required board layout dimensions. Ensure compatibility with the ALVCH series logic family requirements for the target application design.

Selection Notes

Select this component when a 16-bit transparent latch with bus hold functionality is required. The wide supply voltage range from 1.2 V to 3.6 V allows flexibility in low-voltage designs. The inclusion of bus hold inputs simplifies circuit design by removing the need for external resistors for floating inputs.

Part Context

This part belongs to the 74ALVCH series of advanced low-voltage CMOS logic devices. The 'DGG' designation indicates the TSSOP48 plastic thin shrink small outline package. The ':51' suffix typically denotes a specific tape and reel quantity configuration provided by the manufacturer or distributor.

Replacement Considerations

The 74ALVCH16373DL is a pin-compatible alternative available in an SSOP48 package. Verify package dimensions and lead pitch differences between TSSOP48 and SSOP48 before substitution.
