74LVCH322245AEC/G;

Buffers, Drivers, Receivers, Transceivers Overview

The 74LVCH322245AEC/G; is a 32-bit bus transceiver featuring non-inverting, 3-state outputs compatible with bus standards. It includes four output enable (nOE) inputs for cascading and four send/receive (nDIR) inputs for direction control. The device operates within a supply voltage range of 1.2 V to 3.6 V and supports input voltages up to 5.5 V. It integrates 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. The component is specified for operation from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features 5 V tolerant inputs and outputs for interfacing with 5 V logic systems.
• Includes integrated 30 Ω series termination resistors to minimize line noise.
• All data inputs are equipped with bus hold functionality to eliminate external pull-up requirements.
• Complies with JEDEC standard JESD8-B / JESD36 specifications.

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed 3.3 V and 5 V system applications
• High-speed data bus interfaces
• Multi-byte flow-through architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm that the requested variant matches the required LFBGA96 package dimensions and ball configuration. Ensure compatibility with the intended operating voltage and signal integrity requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 32-bit wide interface is required with independent direction control for multiple byte lanes. The integrated termination resistors make it suitable for high-speed designs without external components. Verify that the 1.2 V to 3.6 V supply range aligns with the target system power rails and that 5 V tolerance is necessary for legacy interfacing.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74LVCH family of low-voltage CMOS logic. It is designed as a high-performance bus transceiver for mixed-voltage environments. The part utilizes a plastic fine-pitch ball grid array package to accommodate the high pin count while maintaining a small footprint on the PCB.
