74LVC241AD,112

Overview

The 74LVC241AD,112 is an octal non-inverting buffer and line driver manufactured by NXP Semiconductors. It features 3-state outputs controlled by active LOW (1OE) and active HIGH (2OE) enable inputs. The device operates within a supply voltage range of 1.2 V to 3.6 V and includes Schmitt trigger action at all inputs for tolerance to slow rise and fall times. Inputs are 5 V tolerant, allowing direct interfacing with 5 V logic devices. When disabled, the outputs can withstand up to 5.5 V. The component is housed in a 20-lead SO plastic small outline package (SOT163-1).

Feature Summary

• Octal non-inverting buffer/line driver with 3-state outputs.
• 5 V tolerant inputs and outputs for mixed voltage interfacing.
• Schmitt trigger inputs provide high tolerance to slow signal transitions.
• Outputs remain in high-impedance state when VCC is 0 V.

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments.
• Driving bus lines in digital systems requiring isolation or buffering.
• Interfacing low-voltage logic controllers with 5 V peripheral devices.

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO20 package variant (SOT163-1) as defined in the manufacturer's ordering table. Confirm that the required temperature range aligns with the -40 °C to +125 °C specification listed for this package type. Ensure design compliance with the absolute maximum ratings regarding input clamping currents and power dissipation derating factors above 70 °C.

Selection Notes

Select this component when an octal buffer with independent bidirectional control is required. The dual output enable pins allow separate management of two groups of four bits. The 5 V tolerance feature makes it suitable for legacy system integration where newer low-voltage logic must interface with older 5 V standards without additional level shifting circuitry.

Part Context

This part belongs to the 74LVC family of CMOS logic devices, designed for low-voltage applications. The LVC series offers performance comparable to earlier families while operating at lower supply voltages. The 241A designation specifically indicates the octal buffer configuration with 3-state outputs, distinguishing it from other variants like the 244 or 245 which may differ in inversion or directionality.

Replacement Considerations

Direct functional equivalents include the 74LVC241ADB (SSOP20) and 74LVC241APW (TSSOP20) from the same manufacturer, provided the package footprint matches the design constraints. Cross-manufacturer replacements must verify pin compatibility and electrical characteristics against the original datasheet specifications.
