74LVCH32373AEC/G:5

Latches Overview

The 74LVCH32373AEC/G:5 is a 32-bit transparent D-type latch with 5 V tolerant inputs and outputs, packaged in an LFBGA-96. It operates on a supply voltage range of 1.2 V to 3.6 V. Propagation delay from nDn to nQn is typically 3.0 ns at 3.3 V. The device features four sections of eight latches each, with separate latch enable (nLE) and output enable (nOE) inputs per octal. Quiescent supply current is typically 40 μA. Operating temperature ranges from -40 °C to +85 °C.

Latches Feature Summary

• Features 5 V tolerant inputs and outputs for interfacing with 5 V logic systems.
• Includes bus-hold circuits on all data inputs to eliminate external pull-up resistors.
• Utilizes low inductance multiple power and ground pins to minimize noise and ground bounce.
• Provides direct interface compatibility with TTL levels.

Latches Applications

• Bus-oriented applications requiring 3-state outputs
• Mixed 3.3 V and 5 V environments
• High-performance digital servo processors

Latches Procurement Notes

Verify the specific ordering suffix /G:5 against manufacturer documentation to confirm packaging details such as reel or cut tape specifications. Confirm that the component status aligns with project lifecycle requirements, as availability may vary by region. Ensure the LFBGA-96 package footprint matches the design layout constraints before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring 32-bit data latching with mixed-voltage compatibility. The wide supply voltage range supports operation from 1.2 V to 3.6 V. The inclusion of bus-hold functionality simplifies board design by removing the need for external pull-up components on unused inputs. Verify that the LFBGA-96 package is suitable for the intended PCB assembly process.

Latches Part Context

This part belongs to the 74LVCH series of low-voltage CMOS logic devices manufactured by Nexperia (formerly Philips Semiconductors). It is designed as a high-performance, low-power alternative to advanced CMOS compatible TTL families. The device integrates 32-bit latching capabilities within a single integrated circuit, optimized for bus-oriented applications in consumer and industrial electronics.

Latches Replacement Considerations

Check for updated product specifications or lifecycle notices from the manufacturer. Verify pinout and electrical characteristics against potential substitute parts to ensure functional equivalence in existing designs.

Latches FAQ

How does the bus-hold feature function?

The bus-hold circuit maintains the input state without external pull-up resistors. It switches off when the input voltage exceeds VCC, allowing 5.5 V tolerance on the input pin.

What is the maximum input voltage allowed?

Inputs can accept voltages up to 5.5 V, making them compatible with 5 V logic devices even when the device is powered at lower voltages.
