ISL43112IHZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43112IHZ-T is a single-pole, single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It features a Normally Open (NO) configuration with one circuit channel and a maximum on-resistance of 10 ohms. The device operates within a single supply voltage range of 2.4V to 12V. Key electrical parameters include a maximum turn-on time of 80ns and a turn-off time of 50ns. Charge injection is specified at 8pC, while off-state leakage current reaches a maximum of 1nA. Channel capacitance is 15pF for both source and drain terminals. The component is housed in a 5-SOT (SC-74A/SOT-753) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IHZ' to confirm the tape-and-reel packaging format and lead-free status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for recent product change notices regarding labeling or manufacturing site updates. Ensure availability aligns with project timelines as distribution status may vary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open single-channel switch is required with low on-resistance. Compare against the ISL43111 variant if a normally closed configuration is needed instead. Consider the ISL43121 series for applications requiring dual channels in an SOT-23-8 package. Verify that the 10-ohm on-resistance meets the signal loss requirements of the specific application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4311x family of low-voltage, high-performance analog switches. The family includes the ISL43110 (Normally Open) and ISL43111 (Normally Closed). These devices are designed for portable electronics where low power consumption and small footprint are critical. The ISL43112IHZ-T specifically provides the Normally Open option in the compact 5-SOT package.

Publicly listed substitutes include the 74AHC1G66. Verify pinout compatibility and electrical specifications before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the ISL43112IHZ-T switch?

The ISL43112IHZ-T is a Normally Open (NO) switch, meaning the channel is open (non-conducting) when the control input is low.

What is the maximum operating supply voltage for this device?

The device supports a single supply voltage range from 2.4V to 12V.

Does the ISL43112IHZ-T support dual supply operation?

No, the ISL43112IHZ-T is specified for single-supply operation only. Dual supply variants exist in the broader ISL4311x family but require different part numbers.
