MAX457EPA

Video Amps And Modules Overview

The MAX457EPA is a dual, low-voltage, bidirectional analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a single SPDT configuration per channel within an 8-pin PDIP package. The device operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies of ±2.7 V to ±6 V. Key electrical characteristics include a maximum on-resistance of 35 Ohms and a bandwidth of 150 MHz. Switching times are specified with a maximum turn-on time of 8 ns and a maximum turn-off time of 3 ns. The component supports a continuous current of 10 mA and offers typical off-isolation of -90 dB.

Video Amps And Modules Feature Summary

• Supports both single and dual power supply configurations for flexible system integration
• Provides bidirectional signal switching capability suitable for audio and video applications
• Features low on-resistance to minimize signal attenuation during conduction

Video Amps And Modules Applications

• Audio and video signal routing systems
• Data acquisition systems requiring analog switching
• Communication equipment signal path management

Video Amps And Modules Procurement Notes

Verify the specific suffix 'EPA' to confirm the through-hole PDIP-8 package variant. Confirm RoHS compliance status as manufacturing processes may vary. Check for obsolescence notices given the age of the Maxim Integrated product line. Ensure the supplier provides original manufacturer documentation to validate authenticity against counterfeits.

Video Amps And Modules Selection Notes

Select this component when bidirectional switching with low on-resistance is required in space-constrained through-hole designs. Compare against the MAX457CPI for plastic DIP options or MAX457ESE for surface mount needs. Evaluate thermal dissipation requirements if operating near maximum current limits. Consider the 150 MHz bandwidth suitability for the target signal frequency range.

Video Amps And Modules Part Context

This part belongs to the MAX457 family of low-voltage, bidirectional analog switches. The family includes variants with different packages such as SOIC and TSSOP. These devices are designed for applications requiring reliable switching of audio, video, and data signals with minimal distortion.

Video Amps And Modules Replacement Considerations

MAX457CPI: Same function in PDIP-8 package. MAX457ESE: Surface mount equivalent in SOIC-8. MAX457CEI: Extended temperature version in SOIC-8.
