74HC244PW,118

Overview

The Nexperia 74HC244PW,118 is an octal buffer and line driver featuring non-inverting 3-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device includes two output enable inputs (1OE and 2OE), each controlling four outputs. Propagation delay ranges from 9 ns to 33 ns depending on voltage. Input levels are CMOS compatible.

Feature Summary

• Octal bus interface with non-inverting 3-state outputs
• Wide supply voltage range supporting 2.0 V to 6.0 V operation
• High noise immunity and low power CMOS dissipation
• Input clamp diodes allow interfacing to voltages exceeding VCC

Applications

• Octal bus interface systems
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm RoHS compliance status for the target region. Check the latest product data sheet for any updates to operating conditions or pin configurations before finalizing design integration.

Selection Notes

Select this component for applications requiring high-speed buffering with multiple independent output enables. Ensure the input signal levels match the CMOS specifications. Verify that the thermal dissipation requirements fit within the TSSOP20 package limits for the intended operating environment.

Part Context

This part belongs to the 74HC logic family, designed for high-speed CMOS operations. It serves as a standard solution for expanding digital signals in microprocessor systems. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package variant.

Replacement Considerations

Direct functional equivalents include the 74HCT244PW,118 for TTL-compatible input levels. Other packages such as SO20 (D) or DHVQFN20 (BQ) offer alternative form factors with identical electrical characteristics.
