74LVCH322245AEC

Overview

The 74LVCH322245AEC is a low-voltage CMOS quad bus transceiver featuring 32 channels organized as four 8-bit sections. It operates within a supply voltage range of 1.2 V to 3.6 V and supports 5 V tolerant inputs and outputs, ensuring compatibility with mixed-voltage systems. The device utilizes a 96-pin LFBGA package (13.5x5.5 mm) for surface mount applications. Key electrical characteristics include a propagation delay of 3 ns at 3.3 V, a maximum static current of 40 uA, and output drive capabilities of -24 mA high and 12 mA low. It functions reliably across an extended temperature range from -40°C to +85°C or +125°C depending on the specific variant.

Feature Summary

• Supports bidirectional data transmission between buses operating at different voltage levels
• Provides 5 V tolerance on both input and output pins for safe interfacing
• Features three-state outputs to prevent bus contention when disabled

Applications

• Memory mapping in embedded systems
• Clock driving and buffering
• Bus-oriented communications

Procurement Notes

Verify component authenticity through authorized Nexperia distributors due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level (MSL 2A) requirements before procurement. Check for valid date codes and ensure storage conditions meet J-STD-033 standards to maintain reliability.

Selection Notes

Select this component for designs requiring high-density interconnects with low power consumption. The 96-LFBGA package suits space-constrained PCB layouts. Ensure the system voltage aligns with the 1.2 V to 3.6 V operational range. Consider thermal management for high-temperature environments exceeding standard industrial limits.

Part Context

This part belongs to the Nexperia 74LVCH series, designed for low-voltage applications. It serves as a successor to older TTL-compatible logic families, offering improved speed and lower power dissipation.
