SN74LVC373AQDWREP

Latches Overview

The SN74LVC373AQDWREP is an enhanced product octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and supports mixed-mode operation across all ports. The device features low static current consumption of 10 µA maximum and provides output drive capabilities of -24 mA for high-level and 32 mA for low-level states. Propagation delays are specified at 7.8 ns at 2.7 V and 6.8 ns at 3.3 V. It is housed in a 20-pin TSSOP package and is rated for extended industrial operating temperatures from -55°C to +125°C.

• Provides Ioff support enabling partial power-down mode without back-driving
• Features robust latch performance exceeding JESD 17 standards

Latches Applications

• Automotive infotainment systems
• Instrumentation and control modules
• Industrial communication interfaces
• Portable equipment requiring low power consumption

Latches Procurement Notes

Verify the specific 'AQ' suffix indicates automotive qualification and enhanced product status as defined by Texas Instruments. Confirm the 'DWREP' suffix corresponds to the correct TSSOP-20 package variant and reel packaging specifications. Ensure compatibility with RoHS and REACH directives for your target market. Cross-reference the manufacturer datasheet for exact mechanical dimensions and thermal characteristics before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state outputs in space-constrained applications. The wide temperature range makes it suitable for harsh environments where standard commercial grade parts may fail. Consider the low static current for battery-operated devices. Verify that the 1.65 V to 3.6 V supply range aligns with your system's power rails and logic levels.

Latches Part Context

This part belongs to the SN74LVC373A family of octal transparent D-type latches. The 'A' denotes improved electrical characteristics, while 'Q' signifies automotive qualification. The 'REP' suffix typically indicates a specific tape and reel configuration or enhanced product tier. It serves as a digital storage element for bus holding and interface buffering in complex digital circuits.

Latches Replacement Considerations

Check for SN74LVC373ADWR or SN74LVC373APW for non-automotive equivalents. Verify pinout compatibility with existing PCB layouts. Ensure voltage and temperature ratings meet application requirements if substituting with non-enhanced variants.
