SN74ALVTH16373KR

Overview

The SN74ALVTH16373KR is a 16-bit transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 3.6 V and supports data transfer rates up to 200 MHz. The device utilizes a 56-pin Microstar Junior (BGA) package with dimensions of 7 mm by 4.5 mm. Key electrical characteristics include a propagation delay of 1 ns and an output drive capability of 24 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit data storage with transparent latching functionality for high-speed bus applications.
• Features three-state outputs to facilitate direct connection to system buses without external buffers.
• Designed for low-voltage operation compatible with 3.3 V systems while maintaining fast switching speeds.

Applications

• High-speed data bus buffering in portable electronic devices
• Memory interface circuits requiring 16-bit wide data paths
• Communication equipment utilizing 3.3 V logic levels

Procurement Notes

Verify the specific package type and pinout configuration against your PCB footprint requirements before ordering. Confirm that the 56-pin Microstar Junior BGA assembly process aligns with your manufacturing capabilities. Ensure compatibility with 3.3 V power domains and check for any lead-free or RoHS compliance documentation required for your region's regulatory standards.

Selection Notes

Select this component when a 16-bit width is necessary for data handling efficiency. The three-state output feature simplifies bus architecture design by eliminating the need for additional buffer components. Consider the thermal performance and physical size constraints of the BGA package relative to other available logic families offering similar speed and voltage specifications.

Part Context

This part belongs to the ALVTH series of advanced low-voltage CMOS logic devices. The series is optimized for high-speed operations in 3.3 V environments. It complements other Texas Instruments logic products by providing robust data retention and fast transition times suitable for modern digital systems requiring compact form factors.

Replacement Considerations

Check for SN74ALVCH16373 variants if lower voltage operation down to 1.65 V is required. Verify pin-to-pin compatibility with other 56-pin BGA latches from different manufacturers if supply chain diversification is needed.
