74HCT541PW,112

Overview

The Nexperia USA Inc. 74HCT541PW,112 is an octal non-inverting buffer and line driver featuring three-state outputs housed in a TSSOP20 package (SOT360-1). It operates within a supply voltage range of 4.5 V to 5.5 V. The device includes two active LOW output enable inputs (OE1 and OE2) that force outputs into a high-impedance state when HIGH. Input clamp diodes allow interfacing with voltages exceeding VCC using current limiting resistors. It complies with JEDEC standards JESD8C and JESD7A, supports TTL input levels, and offers ESD protection exceeding 2000 V HBM and 1000 V CDM.

Feature Summary

• Octal non-inverting buffer/line driver with three-state outputs
• Dual active LOW output enables for high-impedance control
• Input clamp diodes for overvoltage interface compatibility
• TTL-compatible input levels with CMOS low power dissipation

Applications

• Bus-oriented communications systems
• Clock buffering and distribution
• Memory address/data bus drivers

Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia documentation, as standard listings typically reference '118'. Confirm the package type matches SOT360-1 (TSSOP20) and ensure the logic family corresponds to HCT specifications rather than HC or VHCT variants. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and exact pinout alignment before procurement.

Selection Notes

Select this component for applications requiring octal data transmission with bus hold capabilities. Ensure the system operates strictly within the 4.5 V to 5.5 V supply range defined for the HCT series. Verify that input signals conform to TTL voltage thresholds. Consider the thermal derating characteristics of the TSSOP20 package if operating near the upper temperature limits.

Part Context

This component belongs to the 74HCT541 family of octal buffers. It shares functional similarities with the 74HC541 but utilizes TTL-compatible input thresholds. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package. It serves as a standard logic interface for driving multiple loads on parallel buses in digital systems.

Replacement Considerations

Direct substitutes include the 74HCT541PW,118 from Nexperia. Other compatible options are the 74HCT541D,652 (SOIC-20 package) and the automotive-grade 74VHCT541PW-Q100J, provided package footprints and electrical specifications align with the design requirements.
