Overview

Description

SN74LVC240APWR is an octal buffer/line driver with 3-state outputs from TI’s LVC family. It provides eight noninverting buffers (A1–A8 → Y1–Y8) in two groups of four, each group with its own active-low enable (G1 and G2). When an enable is low, the corresponding four outputs drive the inputs; when high, those outputs are high-impedance. Operates from 1.65–3.6 V and accepts CMOS/TTL‑like inputs; suitable for fast, low-power buffering and bus isolation between devices or voltage domains. The APWR suffix indicates RoHS-compliant, lead-free packaging options. Typical usage includes microcontroller/data-path buffering, bus driving, and level-shifting between 3.3 V and lower-voltage systems. Key considerations are proper OE timing and avoiding bus contention; refer to the TI datasheet for exact pinout, timing specs, and package options.

Features

SN74LVC240APWR features (concise):
- Octal buffer/driver with 3-state outputs (two 4-bit sections)
- Non-inverting data path
- Two enable inputs (1G and 2G) to independently control each 4-bit bank
- Wide supply range: Vcc 1.65 V to 3.6 V (suitable for 1.8/2.5/3.3 V systems)
- Ioff supporting partial-power-down (no back-powering)
- Outputs go high-impedance when disabled
- CMOS/TTL-compatible input thresholds suitable for common logic levels
- High drive capability for bus driving; fast switching
- ESD protection and robust latch-up performance
- Pb-free, RoHS-compliant APWR packaging; industrial temperature range (typically −40°C to 125°C)
Note: For exact electrical characteristics (drive strength, propagation delays, and guaranteed limits), please refer to the datasheet.

Package

20-pin TSSOP package (PW variant), RoHS-compliant.

Pinout

- Pin count: 20 pins (SOIC/DIP package).
- Function: SN74LVC240APWR is an octal buffer/line driver with 3-state outputs. It provides two 4-bit buffers (A0–A3 to Y0–Y3 and A4–A7 to Y4–Y7) with independent, active-low enables (1G and 2G); data passes A to Y (non-inverting) when enabled; outputs tri-stated when disabled.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: An American multinational semiconductor company that designs and manufactures analog, digital, and mixed-signal integrated circuits and related electronics. It is one of the world’s largest semiconductor manufacturers.

Application

An 8-bit, noninverting buffer/driver with tri-state outputs. Applications: buffering data/address buses between MCUs/CPUs, memory, and peripherals; level shifting between voltage domains (1.65–3.6 V); bus isolation and expansion on backplanes/interconnects; driving high-speed signals for FPGAs, DSPs, LCD controllers; general I/O buffering in embedded systems.

Equivalent

Equivalent parts are other vendors’ 8-bit, dual-4-bit 3-state buffers in the LVC family. Common drop-ins:
- 74LVC240A (Nexperia, formerly Philips)
- uPD74LVC240A (Renesas)
- ALVC240 (Diodes Inc., ALVC240A)
Always verify exact Vcc range (1.65–3.6 V) and OE polarity to ensure full compatibility.
