SN74HCT541PWR 8-Channel Buffer Driver IC – 20-TSSOP (Industrial Grade)

SN74HCT541PWR 8-Channel Buffer Driver IC | Tri-State CMOS Logic in 20-TSSOP

The SN74HCT541PWR is a premium 8-channel buffer / driver IC from Texas Instruments, engineered for high-reliability industrial, automotive, and communication systems. Featuring tri-state outputs, this CMOS logic IC enables efficient bus sharing while maintaining signal integrity in noisy environments — exactly the workhorse part for any board that needs to fan out a small set of MCU GPIOs onto a wider bus or isolate logic blocks during reconfiguration.

With a wide 4.5V-5.5V supply range and ultra-low 8µA static current, the chip suits both energy-sensitive embedded designs and full 5V industrial logic stacks. Output enable (OE) gives clean control of the tri-state behaviour, while the standard 20-TSSOP package (6.5mm × 4.4mm) drops cleanly into high-density PCB layouts.

Tri-State Output & Low-Power CMOS Design for Bus Sharing & Signal Integrity

• Industrial-grade durability — operates flawlessly across the 4.5V-5.5V range in harsh conditions.
• Space-saving 20-TSSOP package — compact 6.5×4.4mm form factor for high-density PCB layouts.
• Ultra-low power consumption — just 8µA static current for energy-sensitive applications.
• Tri-state output control — isolate outputs via the enable pin (OE) to prevent bus contention.
• 6mA output drive — fast signal propagation with minimal noise interference.

Where the SN74HCT541PWR Fits

The classic application is bus driving and isolation — fan out CPU/MCU outputs onto a backplane, level-shift logic between domains, or isolate boards during hot-swap. Common targets: PLC controllers, automotive ECUs, routers, embedded systems with microcontroller-driven peripheral buses, and any board where signal integrity matters more than raw drive strength. Non-inverting logic keeps polarity straightforward, and the tri-state OE pin makes the chip easy to gate from a single MCU GPIO.
