NXP Semiconductors 74HC4353N,652

Overview

74HC4353N,652 from NXP Semiconductors (formerly Philips) is a triple 2-channel analog multiplexer/demultiplexer with address latches, designed for bidirectional signal routing in mixed-signal systems. It features ±5 V analog input voltage range, 60–100 Ω typical ON-resistance at 4.5–9.0 V supply, and dual enable inputs (E1 active LOW, E2 active HIGH) for channel control. It supports analog and digital multiplexing in data acquisition, test equipment, and audio switching applications.

For engineers reviewing the 74HC4353N,652 datasheet, 74HC4353N,652 pinout, 74HC4353N,652 application, or 74HC4353N,652 equivalent, key selection criteria include latch-enabled channel selection, rail-to-rail analog swing (VEE to VCC), break-before-make timing, ON-resistance matching across channels, and compatibility with 2.0–10.0 V CMOS logic supplies.

Technical Context

The 74HC4353N,652 integrates three independent 2:1 analog switches, each with dedicated Y0/Y1 inputs/outputs and a shared Z terminal. Control is implemented via three select lines (S1–S3), two enables (E1/E2), and an active-LOW latch enable (LE) that freezes channel selection on falling edge.

It operates with separate analog and digital supply domains: VCC/GND powers digital inputs (S1–S3, LE, E1, E2), while analog signals swing between VEE (negative rail) and VCC (positive rail), supporting ±5 V operation when VCC = 5 V and VEE = −5 V. The device guarantees ≤9 Ω maximum ΔRON between any two channels at 4.5 V supply.

FAQ

What is the maximum allowable VCC−VEE voltage for the 74HC4353N,652?

The absolute maximum VCC−VEE voltage for the 74HC4353N,652 is 10.0 V, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent damage to the internal analog switches. For ±5 V analog operation, set VCC = +5 V and VEE = −5 V - ensuring the differential remains within the 10.0 V ceiling. Derating is not required at this point, but thermal limits must still be observed per package power dissipation ratings.

Does the 74HC4353N,652 support true bidirectional analog signal flow?

Yes, the 74HC4353N,652 supports fully bidirectional analog signal routing on all Y0/Y1 and Z terminals. Each switch conducts equally well in either direction, with symmetrical ON-resistance and capacitance. This enables use as both multiplexer (Y0/Y1 → Z) and demultiplexer (Z → Y0/Y1) without performance degradation - confirmed by the "analog multiplexer/demultiplexer" designation in the device title and functional diagram.

How does the latch enable (LE) function affect channel selection timing in the 74HC4353N,652?

In the 74HC4353N,652, the LE input operates as an active-LOW transparent latch: when LE is HIGH, S1–S3 inputs pass through directly to control the switches; on the HIGH-to-LOW transition of LE, the current S1–S3 state is latched and held regardless of subsequent changes to S1–S3. This prevents glitches during address updates and ensures stable channel connection during critical intervals like ADC sampling windows.

Can the 74HC4353N,652 operate with VEE tied to GND?

Yes, the 74HC4353N,652 can operate with VEE = GND for unipolar analog signals (0–VCC). In this configuration, it functions as a standard 5 V-tolerant analog MUX/DEMUX. The datasheet explicitly states: "For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically ground)." All electrical characteristics - including ON-resistance, timing, and leakage - are guaranteed under this condition.

What is the significance of the "break before make" behavior in the 74HC4353N,652?

The 74HC4353N,652 incorporates inherent break-before-make timing between Y0 and Y1 connections to the common Z terminal. This ensures the previously selected channel disconnects fully before the newly selected channel connects - preventing momentary shorts that could corrupt sensor readings, damage downstream circuitry, or introduce transient errors in precision analog paths. This behavior is confirmed in the Features list and functional description.
