NXP Semiconductors 74HC4353D,653

Overview

74HC4353D,653 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 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 selection control. It is used in precision data acquisition front-ends where latch-controlled channel persistence and rail-to-rail analog switching are required.

For engineers reviewing the 74HC4353D,653 datasheet, 74HC4353D,653 pinout, 74HC4353D,653 application, or 74HC4353D,653 equivalent, key selection criteria include guaranteed turn-ON/OFF timing (20–29 ns), switch capacitance (5 pF Y-side, 8 pF Z-side), break-before-make behavior, latch enable (LE) timing margins (12–18 ns setup), and compatibility with ±5 V analog rails while driven by 5 V CMOS logic.

Technical Context

The 74HC4353D,653 implements three independent 2:1 analog switches, each with dedicated Y0/Y1 inputs/outputs and shared Z terminal, controlled via three select lines (S1–S3) and latched by LE. Its Si-gate CMOS architecture supports VCC−VEE up to 10 V, enabling operation with split supplies (e.g., VCC = +5 V, VEE = −5 V) for true bipolar analog signal handling.

Digital control pins (S1–S3, E1, E2, LE) operate from 2.0–10.0 V (HC logic), while analog terminals (nY0/nY1/nZ) swing between VEE and VCC. The device includes built-in break-before-make timing to prevent momentary shorting during channel transitions and supports both analog and digital multiplexing modes depending on VEE connection (GND for digital, negative voltage for analog).

FAQ

What is the maximum allowable VCC−VEE voltage for reliable operation of the 74HC4353D,653?

The 74HC4353D,653 has an absolute maximum VCC−VEE rating of 10.0 V. Operation beyond this risks permanent damage to internal switch transistors. For sustained reliability, the recommended operating range is 2.0–10.0 V, with optimal analog performance observed at 4.5–9.0 V. At 2.0 V, ON-resistance becomes highly non-linear, limiting use to digital-only applications. Always ensure VEE remains ≤ VCC and that voltage drops across active switches do not exceed 0.4 V when sourcing current from nZ terminals.

Can the 74HC4353D,653 be used with a single 5 V supply (VEE = GND) for digital multiplexing?

Yes, the 74HC4353D,653 supports digital multiplexing with VEE tied to GND. In this configuration, analog terminals (nY0/nY1/nZ) swing from 0 V to VCC (5 V), matching standard TTL/CMOS logic levels. All timing parameters (e.g., tPHL = 5 ns typ.), ON-resistance (80 Ω typ. at 4.5 V), and control logic remain fully valid. This mode eliminates need for negative supplies in purely digital signal routing, such as selecting between multiple microcontroller peripherals or memory banks.

How does the latch enable (LE) input affect channel selection timing in the 74HC4353D,653?

The LE input controls transparency of the S1–S3 address latches. When LE is HIGH, the 74HC4353D,653 operates transparently - channel selection changes immediately with S1–S3. When LE goes LOW, the current S1–S3 state is latched and held regardless of subsequent address changes. The minimum LE pulse width is 16 ns (HCT) or 80 ns (HC); setup time from Sn to LE is 12 ns (min., HC). This allows precise synchronization of channel updates with system clocks or ADC conversion triggers.

What is the significance of "break before make" behavior in the 74HC4353D,653?

Break-before-make ensures that one analog switch fully turns OFF before the other turns ON during channel transitions - preventing momentary short-circuits between Y0 and Y1 paths. This is critical in applications like sensor calibration where unintended conduction could inject error currents or damage upstream sources. The 74HC4353D,653 achieves this via internal timing control; no external delay circuitry is needed. Typical dead time exceeds 10 ns, verified across all operating voltages and temperatures.

Is the 74HC4353D,653 compatible with 3.3 V microcontroller GPIO for control signals?

Yes, 3.3 V microcontroller GPIO can reliably drive the 74HC4353D,653's digital inputs (S1–S3, E1, E2, LE) because its HC logic family accepts VIH ≥ 3.15 V (min. at VCC = 4.5 V) and VIL ≤ 1.35 V (max. at VCC = 4.5 V). With VCC = 4.5–5.0 V, a 3.3 V HIGH output meets VIH margin comfortably. However, ensure VCC is stable at ≥4.5 V to guarantee full analog performance (e.g., 60 Ω ON-resistance) and avoid degraded timing specs that occur below 4.5 V.
