74LVCH322245AEC,51

Overview

The 74LVCH322245AEC is a 32-bit bus transceiver featuring non-inverting 3-state outputs in both send and receive directions. It includes four output enable (nOE) inputs for cascading and four direction control (nDIR) inputs. The device incorporates integrated 30 Ω series termination resistors to reduce line noise. It supports a supply voltage range of 1.2 V to 3.6 V and accepts input voltages up to 5.5 V, enabling mixed 3.3 V and 5 V applications. It operates from -40 °C to +85 °C and is packaged in a 96-ball LFBGA.

Feature Summary

• Features integrated 30 Ω series termination resistors in both HIGH and LOW output stages to minimize line noise.
• Provides 5 V tolerant inputs and outputs for direct interfacing with 5 V logic devices.
• Includes bus hold circuitry on all data inputs to eliminate the need for external pull-up resistors.
• Offers low inductance multiple power and ground pins to ensure minimum noise and ground bounce.

Applications

• Mixed 3.3 V and 5 V system interconnects
• High-speed data bus transmission
• Cascaded multi-byte data flow architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package details and temperature range. Confirm RoHS compliance status as specifications may change over time. Check for any product discontinuation notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 32-bit bidirectional data transfer with integrated impedance matching. Ensure the application environment stays within the specified -40 °C to +85 °C operating temperature range. Verify that the board layout accommodates the LFBGA96 package dimensions and pin configuration.

Part Context

This part belongs to the NXP 74LVCH family of CMOS low-power bus transceivers. It is designed for high-speed applications requiring 5 V tolerance and low power consumption. The device utilizes a standard multibyte flow-through architecture compatible with common industry pin-outs.

Replacement Considerations

Consult official replacement lists for verified substitutes. Cross-reference pinouts and electrical characteristics carefully if considering alternatives from other manufacturers.
