Philips 74HC/HCT126 Quad Buffer/Line Driver Data Sheet
The Philips 74HC/HCT126 are high-speed Si-gate CMOS devices designed as four non-inverting buffer/line drivers with 3-state outputs. These devices are pin compatible with low power Schottky TTL (LSTTL) and comply with JEDEC standard no. 7A. The 3-state outputs are controlled by active HIGH output enable inputs, allowing the outputs to assume a HIGH impedance OFF-state when enabled.
The document provides comprehensive technical data including quick reference data for propagation delay and power dissipation capacitance, detailed pin descriptions, and AC/DC characteristics for both HC and HCT variants under various temperature conditions.
