74LV373D,118

Latches Overview

The 74LV373D,118 is an octal D-type transparent latch with 3-State outputs manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.0 V to 5.5 V and features separate D-type inputs for each latch alongside common Latch Enable (LE) and Output Enable (OE) inputs. The device provides bus-oriented applications with typical propagation delays of 10 ns at 3.3 V from data input to output and 12 ns from latch enable to output. It accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-State true outputs
• Wide operating voltage range supporting low voltage applications down to 1.0 V
• Common Latch Enable and Output Enable inputs shared across all internal latches
• Bus driver capability with optimized low voltage performance

Latches Applications

• Bus oriented applications requiring data storage and transfer
• Low voltage logic systems compatible with 1.0 V to 3.6 V operation
• TTL interface circuits operating between 2.7 V and 3.6 V supply rails

Latches Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature range. Confirm current production status as legacy components may have limited availability or end-of-life designations. Ensure compatibility with existing PCB footprints and signal integrity requirements before procurement.

Latches Selection Notes

Select this component for designs requiring octal latching with high impedance states. Verify that the required propagation delay meets system timing constraints under specific load conditions. Ensure the operating voltage aligns with the 1.0 V to 5.5 V specification and check thermal dissipation limits for the chosen package style.

Latches Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It is functionally identical to the 74LV573 but utilizes a different pin arrangement. The device is pin and function compatible with 74HC/HCT373 variants, facilitating direct replacement in many standard logic designs while offering improved power efficiency.

Latches Replacement Considerations

The 74LV573 serves as a functional equivalent with distinct pinout configuration. Direct substitution requires verification of pin mapping differences. Other 74LV series latches may offer similar electrical characteristics but require validation of package dimensions and pin assignments.
