74LVT373PW,118

Latches Overview

The 74LVT373PW,118 is a high-performance BiCMOS octal D-type transparent latch with 3-state outputs designed for VCC operation at 3.3 V. It features eight independent latches controlled by a common latch enable (LE) input and output enable (OE) input. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports an ambient temperature range from -40 °C to +85 °C. Propagation delays are specified between 1.9 ns and 5.3 ns depending on the control path and voltage level.

Latches Feature Summary

• Bus hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• TTL input and output switching levels allow interface capability to systems at 5 V supply
• Latch-up protection exceeds JESD78 class II limits
• Power-up reset and power-up 3-state functionality

Latches Applications

• Driving heavily loaded 3-state buses
• Interfacing with MOS memories
• Interfacing with MOS microprocessors

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the manufacturer status and product lifecycle stage before design-in. Ensure the application environment stays within the specified operating temperature and voltage limits defined in the datasheet.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for 3.3 V logic systems. It is functionally identical to the 74LVT573 but utilizes a different pin arrangement. Consider the TSSOP20 package for space-constrained designs requiring surface mount technology.

Latches Part Context

This component belongs to the 74LVT logic family, which provides low-voltage TTL-compatible performance. It is manufactured by NXP Semiconductors under the brand NXP USA Inc. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package variant.

Latches Replacement Considerations

The 74LVT573 is functionally identical but has a different pin arrangement. Other 74LVT series latches may serve as alternatives if pin compatibility is not required.
