SN74ALVCH16373DGGR

Overview

The SN74ALVCH16373DGGR is a 16-bit transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It belongs to the ALVCH logic series and operates within a supply voltage range of 1.65 V to 3.6 V. The device features propagation delays of 4.3 ns and 3.6 ns, with a maximum static current of 40 uA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -24 mA. It is housed in a 48-TSSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports mixed-mode signal operations across various voltage domains
• Provides bus-holding functionality on data inputs to eliminate external pull-up or pull-down resistors
• Includes Ioff support for partial-power-down mode and back-drive protection

Applications

• High-density memory mapping
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the selected variant matches the required lead time and availability constraints for the intended production schedule.

Selection Notes

Select this component when designing systems requiring 16-bit latching with tri-state control at low voltages. Consider the ALVCH series characteristics for applications needing wide voltage flexibility between 1.65 V and 3.6 V. Evaluate the 48-TSSOP package dimensions against available PCB real estate and thermal management requirements.

Part Context
