ISL59442IB

Video Amps And Modules Overview

The ISL59442IB is a single-output 4:1 multiplexing amplifier featuring a fixed gain of 1 and a 1GHz bandwidth. It includes logic inputs for channel selection (S0, S1) and a three-state output control (HIZ). The device operates on dual ±5V supplies with a typical supply current of 18mA. Key electrical parameters include a slew rate of 1452V/µs, 75dB channel isolation, and an input resistance of 10MΩ. It is housed in a 14-lead SOIC package.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as tape and reel options exist alongside bulk units. Confirm RoHS compliance status if lead-free processing is required for the assembly process. Check the datasheet revision date to ensure alignment with current design specifications before finalizing procurement orders.

Video Amps And Modules Selection Notes

Select this component for high-frequency video signal routing where minimal distortion is critical. Ensure the application circuit provides adequate thermal management due to the absence of internal short-circuit protection. Verify that power supply turn-on slew rates remain below 1V/µs to prevent damage during startup sequences.

Video Amps And Modules Part Context

This part belongs to the ISL59442 series of multiplexing amplifiers manufactured by Intersil, now part of Renesas Electronics Corporation. The IB suffix denotes the standard commercial grade version packaged in a 14-lead Small Outline Integrated Circuit (SOIC) format without lead-free plating modifications.

Video Amps And Modules Replacement Considerations

The manufacturer explicitly states that no recommended replacement exists for this discontinued product. Engineers must evaluate alternative high-speed mux-amplifiers based on pin compatibility and bandwidth requirements.

Video Amps And Modules FAQ

How does the HIZ pin function?

The HIZ pin controls the three-state output. A logic high (>2V) places the output in a high-impedance state, while a logic low keeps it active. Internal pull-downs ensure the device remains active if the pin is left floating.

What are the NIC pins used for?

The Not Internally Connected (NIC) pins are not connected to the die. They should be tied to ground to minimize crosstalk between adjacent input channels.
