74ALVCH32501EC,557

Overview

The 74ALVCH32501EC,557 is a 36-bit universal bus transceiver manufactured by NXP USA Inc. It operates within a supply voltage range of 1.2 V to 3.6 V and features non-inverting 3-state outputs. The device supports transparent, latched, or clocked modes via D-type latches and flip-flops. It includes active bus-hold circuitry for unused inputs and provides ±24 mA current drive at 3.0 V. Propagation delay ranges from 2.8 ns to 3.0 ns depending on load capacitance and voltage. The component is housed in an LFBGA114 package.

Feature Summary

• Supports universal bus transceiver functions with configurable transparent, latched, or clocked operating modes
• Features active bus-hold circuitry to maintain valid logic levels on floating data inputs
• Provides direct interface compatibility with TTL logic levels

Applications

• Bus-oriented applications requiring high-performance CMOS data transfer
• Systems utilizing 50 Ω transmission lines at elevated temperatures
• Mixed voltage environments interfacing with 5 V tolerant logic

Procurement Notes

Verify the specific ordering suffix EC,557 against current NXP documentation to confirm package material and temperature range specifications. Confirm that the LFBGA114 plastic fine-pitch ball grid array package matches the design requirements. Ensure compliance with JEDEC standard no. 8-1A is required for the intended application environment.

Selection Notes

Select this component for designs requiring 36-bit bidirectional data flow control with independent direction pins. Consider the wide supply voltage range of 1.2 V to 3.6 V for flexible power domain integration. Evaluate the low power consumption characteristics and direct TTL interface capabilities for mixed-signal system architectures.
