74ALVCH16373DGGRG4

Overview

The SN74ALVCH16373DGGRG4 is a 16-bit transparent D-type latch with 3-state outputs from the Texas Instruments ALVCH logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and features low static current consumption of 40 uA. The device provides a low-level output current of 32 mA and a high-level output current of -24 mA. Propagation delays are specified at 4.3 ns and 3.6 ns. It is housed in a 48-TSSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit data storage capability with non-inverting true logic functionality.
• Features three-state outputs for effective bus-driven applications and system isolation.
• Supports low-voltage operation across a wide range from 1.65 V to 3.6 V.
• Delivers high drive strength suitable for demanding digital interface requirements.

Applications

• High-density memory mapping systems
• Buffering and bus-oriented architectures
• Portable consumer electronics requiring low power consumption

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the TSSOP-48 package dimensions align with your PCB footprint design. Check the datasheet for specific handling instructions regarding moisture sensitivity level and recommended soldering profiles to maintain component integrity during assembly.

Selection Notes

Select this component when designing systems requiring 16-bit latching with tri-state control under low-voltage conditions. It serves as a direct replacement for standard 5V ALVC devices in 3.3V or lower voltage domains. Ensure input voltage levels match the selected supply rail to prevent undefined states. Consider the propagation delay specifications relative to your system clock speed to guarantee timing margins.

Part Context

This device belongs to the Texas Instruments SN74ALVCH series, which combines advanced CMOS technology with low power consumption and high-speed performance. The ALVCH family is designed for applications requiring operation in the 1.65-V to 3.6-V VCC range. The DGGR suffix indicates a 48-pin Thin Shrink Small Outline Package (TSSOP) with a reel packaging format, optimized for automated surface-mount assembly processes.
