74ALVCH162373DLG4

Latches Overview

The SN74ALVCH162373DLG4 is a 16-bit transparent D-type latch with 3-state outputs from the Texas Instruments Widebus family. It operates at supply voltages between 1.65 V and 3.6 V. The device features active bus-hold circuitry on data inputs to eliminate external pullup/pulldown resistors. Output ports include equivalent 26-Ω series resistors to reduce overshoot and undershoot, removing the need for external components. Latch-up performance exceeds 250 mA per JESD 17, and ESD protection exceeds 2000 V (Human-Body Model) and 200 V (Machine Model).

Latches Feature Summary

• Active bus-hold circuitry maintains valid logic states on unused or undriven data inputs without requiring external pullup or pulldown resistors.
• Output ports incorporate equivalent 26-Ω series resistors designed to minimize signal overshoot and undershoot during transitions.
• Latch-up performance exceeds 250 mA according to JESD 17 standards.
• ESD protection capabilities exceed 2000 V via Human-Body Model and 200 V via Machine Model testing.

Latches Applications

• Implementing buffer registers in digital systems.
• Configuring I/O ports for peripheral interfacing.
• Utilizing bidirectional bus drivers for data transmission.
• Serving as working registers within processing units.

Latches Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel configuration. Confirm RoHS compliance status and lead finish specifications against current manufacturing requirements. Ensure the moisture sensitivity level rating aligns with your assembly process constraints. Cross-reference the part marking code to validate authenticity and production batch details before final procurement.

Latches Selection Notes

Select this component when designing low-voltage logic circuits requiring 16-bit latching functionality. The integrated bus-hold feature simplifies board layout by removing passive components. The built-in output resistance reduces electromagnetic interference risks. Verify that the operating voltage range of 1.65 V to 3.6 V matches your system power rails.

Latches Part Context

This device belongs to the Texas Instruments Widebus family, which provides high-density logic solutions. It functions as two independent 8-bit latches or a single 16-bit latch. The DL package variant utilizes an SSOP form factor suitable for surface-mount applications. The GQL and DGG packages offer alternative pinouts for different spatial constraints.
