SN74F126NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F126NS is a quad bus buffer gate manufactured by Texas Instruments, belonging to the SN74F logic series. It features four non-inverting channels with three-state outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from 0°C to +70°C. Key electrical specifications include a propagation delay of 7.5 ns at 5 V, a high-level output current of -15 mA, and a low-level output current of 64 mA. The typical quiescent power supply current is 40 uA.
