SN74LVCH16373ADLR

Latches Overview

The SN74LVCH16373ADLR is a 16-bit transparent D-type latch manufactured by Texas Instruments, designed for operation within a 1.65 V to 3.6 V supply voltage range. It features three-state outputs and is housed in a 48-pin SSOP package with tape-and-reel packaging. The device supports mixed-mode signal operations, allowing compatibility between 3.3 V VCC and 5 V inputs/outputs. Key electrical characteristics include a typical propagation delay of 2.1 ns, output drive currents of 24 mA for both high and low states, and a maximum operating temperature of 85°C.

Latches Feature Summary

• Supports mixed-mode signal operations for interfacing 3.3 V systems with 5 V I/O
• Bus-holding inputs eliminate the need for external pull-up or pull-down resistors
• Ioff circuitry enables partial-power-down mode support for live insertion safety

Latches Applications

• High-density memory mapping applications
• Driving bus-oriented loads
• Clock-data registers and buffers

Latches Procurement Notes

Verify the specific ordering suffix 'ADLR' to confirm the 48-SSOP package type and tape-and-reel shipping configuration. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly standards. Cross-reference the manufacturer part number against official datasheets to validate pinout assignments and electrical specifications before finalizing procurement orders.

Latches Selection Notes

Select this component when a wide supply voltage range from 1.65 V to 3.6 V is required alongside mixed-mode signal compatibility. It is suitable for designs needing bus-holding functionality to simplify schematic design by removing external resistors. Consider this part for applications requiring moderate speed performance with standard 24 mA drive capability in a compact surface-mount package.

Latches Part Context

This device belongs to the Texas Instruments LVCH (Low-Voltage CMOS High-Speed) logic family. It provides 16 bits of storage with tri-state control, serving as a bridge between internal logic and external buses. The SN74LVCH16373ADLR variant specifically denotes the SSOP package form factor and reel packaging, distinguishing it from other physical configurations within the same logical series.

Latches Replacement Considerations

SN74LVCH16373ADL is a tube-packaged alternative with identical electrical characteristics. SN74LVCH16373ADGGR offers the same function in a TSSOP-48 package. Verify package dimensions and thermal properties when substituting these variants.
