Vue d'ensemble

Description

The SN74AHC540PWR is TI’s octal buffer/line driver with 3-state outputs (non-inverting). It provides eight buffering stages, arranged in two groups of four, each with its own output-enable control. When an OE is active, the corresponding inputs pass to the outputs; when inactive, the outputs are high impedance, allowing bus sharing.
Key points:
- AHC CMOS performance: fast operation with relatively low power, typically usable from about 2.0 to 5.5 V.
- Two independent OE inputs enable/tri-state the two 4-bit sections.
- Packaged in a thermally enhanced PWR variant (PowerPAD/exposed pad) for better heat dissipation.
Common uses:
- Buffering and isolating data buses between a microcontroller/CPU and peripherals or memory.
- Providing controlled tri-state drive on multi-device buses.
Note: Check the TI datasheet for exact pinout, drive strength, propagation delay, and voltage/temperature specs for your chosen package.

Features

- 8-bit noninverting buffer/line driver with 3-state outputs (A0–A7 to Y0–Y7)
- Output Enable (OE) input, active-low, to tri-state all outputs
- Vcc range: 2.0 V to 5.5 V (suitable for 3.3 V and 5 V logic)
- Fast Advanced CMOS (AHC) technology for high-speed operation
- Input thresholds CMOS-compatible at Vcc
- Each output can source/sink significant current for bus driving (typical I/O drive suitable for parallel data buses)
- Low static/dynamic power consumption
- Industrial temperature range (-40°C to 125°C)
- Package variant with PowerPAD/exposed pad (PWR) for improved thermal performance
- 3-state bus-oriented part suitable for buffering/address/data bus applications

Package

The SN74AHC540PWR is a 20‑pin PowerPAD (thermally enhanced) package; the “PWR” suffix denotes the PowerPAD variant.

Pinout

Pin count: 20 pins (PowerPAD package variant).
Function: SN74AHC540PWR is an octal buffer/line driver with tri-state outputs. It provides eight non-inverting data buffers (A0–A7 to Y0–Y7) controlled by a single enable input (G/OE). When enabled, Y = A; when disabled, all outputs go to high impedance.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and digital integrated circuits; one of the world’s largest chipmakers, headquartered in Dallas, Texas (NYSE/NASDAQ: TXN).

Application

An 8-bit, non-inverting buffer/line driver with 3-state outputs and a low-active enable. Applications: buffering and isolating wide data/address buses between CPUs, memories, and peripherals; fan-out expansion to drive multiple devices; tri-state bus sharing with a single control; interfacing within a common Vcc domain while reducing driver load.

Equivalent

SN74AHC540PWR is an octal, non-inverting buffer/driver with 3-state outputs. Equivalents include: 74AHC540 (same function), 74HC540 and 74HCT540 (TTL/non-TTL input thresholds), and low-voltage variants like 74LV540 and 74LVC540. Vendors: TI, NXP, ON Semiconductor, Renesas, etc. Choice depends on supply voltage and input thresholds.
