74LVCH322244AEC,51

Overview

The 74LVCH322244AEC,51 is a 32-bit non-inverting buffer/line driver with 3-state outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 1.2 V to 3.6 V and features inputs tolerant to 5 V signals. The device includes integrated 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. All data inputs are equipped with bus hold circuits to maintain valid logic levels without external pull-up resistors. It is housed in a 96-ball LFBGA package (SOT536-1) measuring 13.5 x 5.5 mm.

Feature Summary

• Integrated 30 Ω series termination resistors in output stages for noise reduction
• Bus hold functionality on all data inputs to eliminate external pull-up requirements
• 5 V tolerant inputs and outputs for mixed voltage interfacing
• Low inductance multiple power and ground pins to minimize noise and ground bounce

Applications

• Mixed 3.3 V and 5 V logic environments
• Bus-oriented applications requiring 3-state control
• High-speed data transmission lines with termination needs

Procurement Notes

Verify the specific ordering suffix EC,51 against the manufacturer's current production status, as availability may vary. Confirm that the LFBGA96 package dimensions and ball mapping match the design footprint. Ensure compliance with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 relevant to the target supply voltage range. Check for RoHS compliance documentation if required by the end application.

Selection Notes

Select this component when designing systems requiring 32-bit wide buffering with integrated termination. It is suitable for applications needing direct interface with TTL levels and 5 V tolerant I/Os. Consider the low power consumption characteristics and the wide operating temperature range from -40 °C to +125 °C for industrial or automotive-grade environments where thermal stability is critical.

Part Context

This part belongs to the 74LVCH family of low-voltage CMOS logic devices. It shares architectural similarities with other 74LVCH buffers but is distinct due to its 32-bit width and integrated termination resistors. The device complements the 74LVCH322245A transceiver series by providing unidirectional buffering capabilities with similar electrical characteristics and pinout compatibility considerations.

Replacement Considerations

Direct substitutes include the 74LVCH322244ADGG,118. Verify pinout compatibility and electrical specifications before substitution.
