74ABT126D,602

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT126D,602 is a quad buffer and line driver featuring BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and provides TTL-compatible direct interface capabilities. The device includes four non-inverting buffers with three-state outputs controlled by individual output enable inputs (nOE). It supports partial power-down applications through integrated IOFF circuitry, which prevents damaging backflow currents when the device is powered down. The component is housed in an SO14 plastic small outline package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• BiCMOS high-speed performance combined with strong output drive capability
• Integrated IOFF circuitry enabling safe partial power-down mode operation
• Three-state outputs allowing live insertion and extraction on bus lines
