74LV244N,112

Overview

The 74LV244N,112 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.0 V to 5.5 V. The device provides two independent output enable inputs (1OE and 2OE), each controlling four outputs. It accepts TTL input levels when the supply voltage is between 2.7 V and 3.6 V. Static characteristics include an input leakage current maximum of 1.0 μA at 5.5 V and a supply current maximum of 160 μA at 5.5 V. Propagation delay ranges from 8 ns typical at 3.3 V to 15 ns maximum at 4.5 V to 5.5 V.

Feature Summary

• Provides eight non-inverting buffered outputs with three-state capability controlled by separate enable inputs.
• Supports wide supply voltage operation from 1.0 V to 5.5 V for compatibility with various logic families.
• Includes input clamp diodes to allow interfacing with voltages exceeding VCC using current limiting resistors.
• Features latch-up protection exceeding 100 mA per JESD 78 Class II Level B standards.

Applications

• Memory address buffering
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature range. Confirm that the component meets RoHS compliance requirements if applicable to the design. Check for any recent discontinuation notices or lifecycle status updates directly from Nexperia before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high-speed data buffering across multiple buses. Ensure the operating voltage aligns with the 1.0 V to 5.5 V specification. Consider the thermal derating characteristics if operating near the upper temperature limits. Verify that the load capacitance requirements are met to maintain signal integrity within specified propagation delays.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. It serves as an octal buffer/line driver variant within the broader 74xx family. The device is designed for general-purpose digital applications requiring bus driving capabilities with low power consumption and high noise immunity.

Replacement Considerations

Consult official Nexperia cross-reference guides for verified substitutes. Ensure replacement parts match the pinout, voltage range, and electrical characteristics. Verify package compatibility if physical footprint constraints exist.
