74LV541DB,118

Overview

The NXP USA Inc. 74LV541DB,118 is a low-voltage Si-gate CMOS octal buffer and line driver featuring non-inverting outputs with 3-state capability. It operates within a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device utilizes two active LOW output enable inputs (OE1 and OE2) to control the high-impedance OFF-state. It is housed in an SSOP20 plastic shrink small outline package (SOT339-1) with a body width of 5.3 mm and supports temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Octal non-inverting buffer/line driver with 3-state outputs controlled by dual active LOW enable inputs
• Optimized for low voltage applications with operation down to 1.0 V
• Compatible with 74HC541 and 74HCT541 pinouts and functions
• ESD protection exceeding 2000 V (HBM) and 200 V (MM)

Applications

• Bus driver applications in mixed voltage environments
• Low voltage logic translation between different voltage domains
• Line driving for digital signal transmission

Procurement Notes

Verify the specific ordering suffix ',118' against current NXP documentation to confirm packaging details and availability status. Ensure the required operating temperature range (-40 °C to +85 °C or -40 °C to +125 °C) matches the specific batch designation. Confirm RoHS compliance status as indicated in the latest product data sheet revision.

Selection Notes

Select this component when an octal buffer with 3-state outputs is required for low-voltage systems operating between 1.0 V and 3.6 V. It serves as a direct pin-compatible replacement for 74HC541 and 74HCT541 devices. Consider the SSOP20 package constraints and thermal derating characteristics above 60 °C for power dissipation calculations.

Part Context

The 74LV541 series belongs to NXP's low-voltage CMOS logic family. The 'DB' suffix denotes the SSOP20 package variant, while ',118' typically indicates specific tape-and-reel packaging configurations used by distributors. This part is functionally equivalent to other 74LV541 variants but differs in physical packaging and shipping format.

Replacement Considerations

Pin-compatible replacements include 74HC541 and 74HCT541, though these operate at higher voltages. Other 74LV541 variants with different packages (e.g., DIP20, SO20, TSSOP20) are functionally identical but require footprint verification.
