SN74LVCZ240APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCZ240A is an octal buffer with Schmitt-trigger inputs and 3-state outputs, manufactured by Texas Instruments. It operates from a supply voltage of 2.7V to 3.6V. The device features balanced CMOS outputs capable of sinking and sourcing similar currents. Inputs accept voltages up to 5.5V, supporting mixed-mode signal operation with 3.3V VCC. Maximum propagation delay is 6.5ns at 3.3V. Typical output ground bounce is 2V at VCC = 3.3V. Latch-up performance exceeds 100mA per JESD 78.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (PW, DW, or NS) required for the design, as dimensions differ. Confirm that the application environment stays within the -40°C to +85°C operating temperature range. Ensure input signals do not exceed the absolute maximum ratings to prevent damage. Check for updated documentation revisions before finalizing the bill of materials.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 3.3V logic interfaces with 5V tolerant systems are required. The balanced output drive supports high-speed digital signaling. Verify that the load capacitance does not exceed 50pF to maintain specified switching characteristics. Consider the thermal metrics if multiple devices operate simultaneously in enclosed spaces.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVCZ family, designed for low-voltage applications. It provides octal buffering capabilities with independent control over two banks of four drivers each. The inclusion of Schmitt triggers enhances signal integrity in noisy environments compared to standard CMOS buffers.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the high-impedance state maintained during power-up?

Both OE pins must be tied to VCC through a pull-up resistor to confirm the high-impedance state during power-up or power-down.

What happens to the outputs when the supply pin is held at 0V?

The device disables all outputs regardless of input voltages, preventing current sourcing or sinking, defined by the Ioff specification.
