74ALVC16373DT

Latches Overview

The onsemi 74ALVC16373DT is a 16-bit transparent D-type latch belonging to the ALVCH logic family. It features two independent 8-bit functional blocks with three-state outputs, operating within a supply voltage range of 1.65 V to 3.6 V. The device provides low static current consumption of 40 µA and supports high drive currents of ±24 mA. Propagation delays are specified at 4.3 ns at 2.7 V and 3.6 ns at 3.3 V. It is housed in a 48-TSSOP package and operates over an industrial temperature range of -40°C to +85°C.

Latches Feature Summary

• Provides 16-bit parallel data storage capability through two independent 8-bit latch sections.
• Features three-state outputs for direct bus driving applications without external pull-up resistors.
• Supports low-voltage operation from 1.65 V to 3.6 V with high noise immunity characteristics.

Latches Applications

• Parallel data buffering in microprocessor systems
• I/O port expansion for embedded controllers
• Memory address latching in storage architectures

Latches Procurement Notes

Verify component authenticity against official onsemi datasheets due to market availability variations. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Ensure design compatibility with 1.65 V to 3.6 V supply rails and TSSOP-48 footprint requirements during procurement planning.

Latches Selection Notes

Select this component when designing systems requiring 16-bit parallel data retention with low power consumption. The ALVCH series offers superior speed compared to standard LVC devices while maintaining compatibility with 3.3 V logic levels. Verify that the application environment remains within the specified -40°C to +85°C operating temperature range for optimal performance.
