Onsemi 3-State Inverting Octal Buffer SOIC 20 2V to 6V

The Onsemi 3-State Inverting Octal Buffer is a SOIC 20 integrated circuit that provides eight inverting buffer outputs with 3-state control, operating across a 2V to 6V supply range.

Overview

This inverting octal 3-state buffer is built using advanced silicon-gate CMOS technology. It delivers high drive current outputs, enabling high-speed operation even when driving large bus capacitances. The device achieves speeds comparable to low-power Schottky devices while retaining the high noise immunity and low power consumption associated with CMOS circuitry.

The buffer offers a fan-out of 15 LS-TTL equivalent inputs, allowing it to drive multiple loads effectively. Its 3-state control gate operates as a two-input NOR, so that if either G1 or G2 is HIGH, all eight outputs enter the high-impedance state, allowing connection to system buses. The pin-out is optimised for enhanced PC board layout, with inputs and outputs arranged for convenience.
