Overview
The PS381ESE is a precision analog switch manufactured by Diodes Incorporated, operating within the PS381/PS383/PS385 series. It features two normally open (NO) switches and is housed in a 16-pin Narrow SO package. The device supports single supply voltages from +3V to +15V or split supplies from +3V to +8V. Electrical specifications at V± = ±5V include an on-resistance of 26Ω typical and 52Ω maximum, with channel matching under 2Ω and flatness under 4Ω. Leakage current is less than 2.5nA at +85°C. Switching times are typically 71ns for turn-on and 25ns for turn-off.
Feature Summary
- Features low on-resistance and minimal charge injection to reduce distortion and step errors in sample-and-hold circuits.
- Provides rail-to-rail analog signal dynamic range while maintaining low power consumption below 1mA.
- Ensures signal integrity through break-before-make switching action that protects against momentary crosstalk.
Applications
- Instrumentation and Automatic Test Equipment (ATE)
- Sample-and-hold circuits
- Audio switching and routing systems
- Telecommunication systems including PBX and PABX
- Battery-powered systems
Procurement Notes
Verify the ordering suffix 'ESE' corresponds to the -40°C to +85°C temperature range and the 16-pin Narrow SO package configuration. Confirm compatibility with TTL/CMOS logic levels for control signals. Ensure voltage ratings align with system requirements before integration.
Selection Notes
Select this component when high precision and low distortion are required for analog signal routing. The dual NO configuration suits applications needing independent channel control. Consider the narrow SO package for space-constrained designs requiring industrial temperature operation.
Part Context
This part belongs to the PS381/PS383/PS385 family of precision, medium-voltage analog switches. These devices serve as improved second sources for MAX381/MAX383/MAX385 components. The series is designed for applications demanding low glitching and high off-isolation across varying supply conditions.
Replacement Considerations
The datasheet identifies the PS381/PS383/PS385 as improved second sources for MAX381/MAX383/MAX385. Verify pinout and electrical parameter compatibility before substituting these legacy parts.
