74HCT126D,653 Quad Buffer/Line Driver IC with 3-State Outputs | High-Speed CMOS | SOIC-14 SMD

Description

The 74HCT126D,653 is a high-speed, silicon-gate CMOS Quad Buffer/Line Driver featuring 3-state outputs. It contains four independent buffers, each with its own output enable (OE) input. When the OE input is driven HIGH, the buffer passes the data from the input to the output. When the OE input is driven LOW, the output is placed into a high-impedance (OFF) state, effectively disconnecting it from the circuit. This makes the 74HCT126 an ideal choice for bus-oriented systems where multiple devices must share a common data line without causing signal contention.

As part of the HCT series, this device is designed to be TTL-compatible, allowing it to interface seamlessly with standard 5V TTL logic levels while maintaining the efficiency and low power consumption of CMOS technology. The compact SOIC-14 surface-mount package is optimized for space-constrained PCB layouts and automated manufacturing processes.
