HI4P0548-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI4P0548-5 is a high-performance analog multiplexer switch IC manufactured by Intersil, now part of Renesas Electronics. It features an 8:1 channel configuration with overvoltage protection (OVP) on all inputs and outputs, ensuring robust operation in demanding environments. The device utilizes a PLCC package and supports dual supply voltages up to 22V maximum. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, with both turn-on and turn-off times specified at a maximum of 300 ns. It operates within a temperature range of 0°C to +75°C and draws a maximum supply current of 2 mA.
