SN74LVCZ240ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCZ240ADBR is an octal buffer/driver with 3-state outputs designed for 2.7 V to 3.6 V VCC operation. It features two 4-bit buffers with separate output-enable inputs. Inputs accept voltages up to 5.5 V, supporting mixed-mode signal operation on all ports. The device provides a maximum propagation delay of 6.5 ns at 3.3 V and includes Ioff and power-up 3-state support for hot insertion.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage with 3.3-V VCC
• Includes Ioff circuitry to disable outputs and prevent damaging current backflow when powered down
• Power-up 3-state circuitry places outputs in high-impedance state during power transitions
