SN74LV373AIPWRQ1

Latches Overview

The SN74LV373AIPWRQ1 is an automotive-grade octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode voltage operation across all ports. The device features three-state outputs and is housed in a TSSOP-20 package. Propagation delay varies with voltage: 21 ns at 2.5 V, 17 ns at 3.3 V, and 10.5 ns at 5 V. Static current is 20 uA. Low-level output current is 32 mA, while high-level output current is -16 mA. It meets AEC-Q100 qualification standards and functions between -40°C and +85°C.

Latches Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for durable performance in vehicle environments.
• Supports mixed-mode voltage operation allowing inputs and outputs to operate at different voltage levels simultaneously.
• Provides Ioff support enabling partial power-down mode to protect downstream components during system sleep states.

Latches Applications

• Printer systems
• Motor control circuits
• Network switches
• Server motherboards
• Wireless infrastructure

Latches Procurement Notes

Verify the complete part number including suffixes such as IPWRG4 or Q1 to ensure correct automotive qualification and packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before procurement. Cross-reference datasheet revisions to validate electrical characteristics against specific design requirements. Ensure compatibility with intended operating temperature ranges and voltage supplies.

Latches Selection Notes

Select this component when designing automotive logic circuits requiring robust latch functionality with mixed-voltage interface capabilities. The LV series offers lower power consumption compared to standard TTL alternatives. Verify that the TSSOP-20 package fits the available PCB footprint. Consider propagation delays relative to system clock speeds to ensure timing margins are sufficient for reliable data capture and storage operations.

Latches Part Context

This device belongs to the SN74LV373A family of octal transparent D-type latches. It shares functional similarities with non-automotive variants like the SN74LV373AIPWR but includes additional qualification for automotive use. The family is designed for high-speed memory addressing and buffer applications where low power and wide voltage tolerance are critical.
