CD74HCT4053E – HARRIS

Overview

The Texas Instruments CD74HCT4053E is a high-performance, triple 2-channel analog multiplexer/demultiplexer designed for robust signal routing in digital and analog systems. Its key operational characteristic is the ability to switch signals with low distortion and minimal insertion loss up to a 200 MHz bandwidth, making it suitable for demanding applications. A critical design consideration when utilizing this device is the trade-off between its low static current consumption (16 µA max) and the inherent on-resistance of 130 Ohms, which can impact signal integrity in high-impedance circuits, necessitating careful impedance matching and filtering.
