The CD74HCT153E is a high-speed CMOS logic dual 4-to-1 line selector/multiplexer, designed to select one of four sources for each section via common select inputs, S0 and S1. When the enable inputs (1E, 2E) are high, the outputs are in the low state, providing a versatile selection mechanism in digital systems.
This component features buffered inputs and outputs, offering standard outputs capable of driving 10 LSTTL loads and bus driver outputs capable of driving 15 LSTTL loads. It operates within a wide temperature range of -55°C to 125°C, supporting applications in varied environmental conditions. Balanced propagation delay and transition times, along with significant power reduction compared to LSTTL logic ICs, make it suitable for high-performance systems.
