Product Introduction

Overview

The SN74HCT541NSR is an octal buffer and line driver produced by Texas Instruments. This device is designed to offer high performance and facilitate easy printed circuit board layout due to its data flow-through pinout, where all inputs are on one side and all outputs are on the opposite side of the package.

It operates within a voltage range of 4.5 V to 5.5 V, making it compatible with TTL (Transistor-Transistor Logic) systems. The device features 3-state outputs, which can be set to a high-impedance state when either of the output-enable inputs is high. This functionality is particularly useful in bus-oriented systems where multiple devices need to share the same data lines.

  • High-current 3-state outputs that can drive up to 15 LSTTL loads or interface directly with system bus.
  • Low power consumption with a maximum supply current (ICC) of 80 µA.
  • Typical propagation delay time (tpd) of 12 ns at 5.5 V.
  • ±6-mA output drive at 5 V.
  • Low input current of 1 µA max.
  • Inputs are TTL-voltage compatible.
  • Data flow-through pinout for easy PCB layout.

Applications

The SN74HCT541NSR is suitable for various applications requiring high-speed data transmission and buffering, such as:

  • Bus-oriented systems where multiple devices share the same data lines.
  • High-speed digital circuits requiring low propagation delay.
  • Systems needing to drive multiple LSTTL loads.
  • Embedded systems and microcontrollers requiring buffer and line driver functionality.
