74LV244D,118

Overview

The 74LV244D,118 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 and supports two independent output enable inputs (1OE and 2OE), each controlling four outputs. The device accepts TTL input levels between 2.7 V and 3.6 V. Propagation delay ranges from 9 ns at 3.3 V to 50 ns at 1.2 V. It includes input clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Features two independent output enables for separate control of eight outputs
• Includes input clamp diodes allowing interface to voltages higher than the supply rail
• Complies with JEDEC standards for low-voltage applications across multiple voltage ranges

Applications

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

Procurement Notes

Verify the specific package type against the ordering information table. Confirm that the SO20 plastic small outline package matches the SOT163-1 version designation. Ensure the temperature range requirement aligns with the -40 °C to +125 °C specification provided in the datasheet.

Selection Notes

Select this component when an octal buffer with three-state capability is required. Verify that the operating voltage falls within the 1.0 V to 5.5 V range. Check if the propagation delay specifications meet the system timing requirements at the intended supply voltage.

Part Context

This part belongs to the Nexperia 74LV logic family, designed for low-voltage CMOS applications. It serves as an octal buffer or line driver. The device provides high drive capability while maintaining low power dissipation characteristics typical of modern CMOS technology.

Replacement Considerations

The 74LV244PW,118 is a documented alternative offering the same electrical functionality in a TSSOP20 package.
