74LVCH322245AEC/G:

Overview

The 74LVCH322245AEC is a 32-bit bus transceiver featuring non-inverting 3-state outputs. It operates with a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device includes four output enable (nOE) and four send/receive (nDIR) control inputs. It utilizes an LFBGA96 package measuring 13.5 x 5.5 mm. Operating temperatures range from -40 °C to +85 °C.

Feature Summary

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

Applications

• Mixed 3.3 V and 5 V system applications
• High-speed data transmission buses
• Multi-byte flow-through standard pin-out architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation, as suffixes may indicate variations in packaging or tape-and-reel specifications. Confirm that the component status remains active for production use, as older revisions may have been superseded by newer product data sheets. Ensure compatibility with the required temperature range and package dimensions before finalizing procurement.

Selection Notes

Select this component when designing interfaces between 3.3 V and 5 V logic domains requiring high-speed data transfer. The integrated termination resistors make it suitable for applications where signal integrity is critical without adding external components. Consider the LFBGA96 package constraints regarding PCB layout and thermal management during the selection process.

Part Context

This part belongs to the 74LVCH family of CMOS logic devices, designed for low-voltage operation. It serves as a bidirectional bus transceiver within the broader category of digital logic ICs. The device is manufactured by NXP Semiconductors and follows JEDEC standards for interface compatibility.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same 32-bit width, 3-state output capability, and LFBGA96 package footprint. Verify that alternative parts support the required 5 V tolerance and operating voltage range.
