Product details
Overview
74HCT4353D,118 from NXP Semiconductors (formerly Philips) is a triple 2-channel analog multiplexer/demultiplexer with address latches and dual enable control. It features ±5 V analog input range, 70 Ω typical ON-resistance at 5 V supply, and TTL-compatible digital inputs. It operates as a bidirectional signal routing device in mixed-signal systems requiring channel selection with latch hold functionality - e.g., data acquisition front-ends interfacing multiple sensors to a single ADC.
For engineers reviewing the 74HCT4353D,118 datasheet, 74HCT4353D,118 pinout, 74HCT4353D,118 application, or 74HCT4353D,118 equivalent, key selection criteria include its dual-enable architecture (E1 active LOW, E2 active HIGH), latch enable (LE) for static channel selection, ±5 V analog swing capability, 21 ns typical turn-ON time, and SO16 package compatibility with industrial PCB layouts.
Technical Context
The 74HCT4353D,118 implements three independent 2:1 analog switches, each with dedicated Y0/Y1 inputs/outputs and a shared Z terminal. Channel selection is controlled by three select lines (S1–S3), latched via LE (active LOW), enabling stable routing without continuous digital bus activity.
It supports dual-supply operation: VCC/GND powers digital logic (4.5–5.5 V), while analog paths span VEE (−5 V) to VCC (+5 V), enabling true bipolar signal handling. All switches exhibit built-in "break-before-make" behavior and deliver ≤68 ns maximum turn-OFF time under 5 V/−5 V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - ensures TTL-level compatibility with standard 5 V microcontrollers and logic families. |
| Analog Voltage Range | VEE = −5 V to VCC = +5 V - enables direct routing of ±5 V sensor signals without level-shifting circuitry. |
| ON Resistance (RON) | 70 Ω typ. at VCC−VEE = 10 V - minimizes signal attenuation and gain error in precision analog paths. |
| Turn-ON Time (tPZH) | 21 ns typ. at E1/E2/Sn to output - supports multiplexing of signals up to ~10 MHz without timing-induced distortion. |
| Switch Capacitance (CS) | 5 pF (Y), 8 pF (Z) - limits charge injection and crosstalk in high-impedance sampling circuits. |
| Crosstalk (1 MHz) | −60 dB between switches - preserves signal integrity when routing multiple analog sources on shared PCB traces. |
| Input Leakage Current | ≤1.0 µA max - prevents loading of high-Z sensor outputs such as piezoelectric or pH electrodes. |
Pinout & Package
74HCT4353D,118 is housed in a 16-pin small-outline (SO16) package per JEDEC MS-012, with 1.27 mm pitch and gull-wing leads. Thermal dissipation is rated at 500 mW (derated above +70 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 6, 12, 13, 15, 16, 17 | Independent I/O (1Y0, 1Y1, 2Y0, 2Y1, 3Y0, 3Y1) | Bidirectional analog terminals - connect to individual sensor channels or DAC outputs. |
| 5, 18, 19 | Common I/O (1Z, 2Z, 3Z) | Shared analog path - typically routed to ADC input, op-amp summing node, or test point. |
| 7 | E1 (Enable 1) | Active LOW global enable - used for power-gating groups of multiplexers or fault isolation. |
| 8 | E2 (Enable 2) | Active HIGH global enable - allows OR-style enable logic with other system signals. |
| 9 | VEE | Negative supply rail - must be connected to −5 V (or GND for unipolar operation) to define analog swing limits. |
| 10 | GND | Digital ground reference - separate from analog ground in mixed-signal designs to reduce noise coupling. |
| 11 | LE (Latch Enable) | Active LOW - freezes S1–S3 state to maintain channel selection during digital bus contention or clock pauses. |
| 14, 3 | n.c. | No internal connection - left floating; no PCB trace required. |
| 20 | VCC | +5 V digital supply - powers logic control circuitry only; does not source analog current. |
Key Features
| Feature | Design Value |
|---|---|
| Triple 2:1 analog switch array | Enables simultaneous routing of three independent signal pairs - ideal for multi-channel data loggers with shared ADC resources. |
| Address latching (LE input) | Eliminates need for continuous S1–S3 bus drive, reducing MCU GPIO usage and digital noise coupling into analog sections. |
| Logic-level translation | Accepts TTL-level inputs while switching ±5 V analog signals - removes external level shifters in 5 V system designs. |
| Break-before-make switching | Prevents momentary short-circuits between Y0/Y1 during channel transitions - critical for avoiding glitches in feedback loops or powered signal sources. |
| Low OFF-state leakage (≤1 µA) | Maintains accuracy in high-impedance measurement paths (e.g., thermocouple amplifiers) without adding guard-ring PCB layout complexity. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4353D,118 | CMOS logic inputs; VCC = 2–10 V; RON = 90 Ω typ. at 5 V | Requires level-shifting for TTL control buses; wider supply range suits battery-powered systems | Select when operating outside 4.5–5.5 V or interfacing with 3.3 V logic via resistive dividers |
| ADG732BRUZ | 32-channel CMOS mux; 4.5 Ω RON; SPI interface; 2.7–5.5 V supply | Serial control eliminates 5 GPIOs but adds firmware overhead; higher channel count increases footprint | Select for high-channel-count systems where SPI configurability outweighs GPIO simplicity |
Compared with 74HC4353D,118 and ADG732BRUZ, the 74HCT4353D,118 uniquely balances TTL compatibility, triple-channel integration, and latch-based static routing - making it optimal for fixed-configuration, medium-channel analog systems where deterministic timing and minimal MCU resource use are prioritized.

FAQ
What is the maximum allowable voltage difference between VCC and VEE for the 74HCT4353D,118?
The 74HCT4353D,118 specifies a maximum VCC − VEE of 10.0 V. At nominal operation, this permits configurations such as VCC = +5 V and VEE = −5 V. Exceeding this limit risks permanent damage to the internal analog switches. The device's absolute maximum ratings confirm ±11.0 V on VCC and −0.5 V minimum on VEE, but the differential constraint governs safe analog signal swing.
Can the 74HCT4353D,118 operate with VEE tied to GND?
Yes - the 74HCT4353D,118 supports unipolar operation with VEE = GND. In this mode, analog signals swing from 0 V to VCC (4.5–5.5 V), functioning as a standard 5 V analog multiplexer. The ON-resistance remains 70 Ω typ., and all timing parameters retain their specified values. This configuration simplifies power design in purely positive-rail systems.
Does the 74HCT4353D,118 require external pull-up or pull-down resistors on its digital control pins?
No - the 74HCT4353D,118 has TTL-compatible inputs with defined VIH (≥2.0 V) and VIL (≤0.8 V) thresholds. Its input leakage current is ≤1.0 µA, so direct connection to 5 V logic outputs (e.g., MCU GPIO, 74-series gates) is sufficient. Pull resistors are unnecessary unless implementing wired-OR logic or open-collector interfaces, which are not native to this device's enable/latch architecture.
How does the latch enable (LE) function affect channel selection timing in the 74HCT4353D,118?
When LE is HIGH, the 74HCT4353D,118 operates transparently: changes on S1–S3 immediately update the selected channel. When LE transitions LOW, the current S1–S3 state is latched, freezing channel selection regardless of subsequent S-line activity. This allows the MCU to reconfigure its address bus for other tasks while maintaining stable analog routing - critical for glitch-free sampling in time-sensitive applications.
Is the 74HCT4353D,118 pin-compatible with the 74HC4353D,118?
Yes - the 74HCT4353D,118 and 74HC4353D,118 share identical pinout, package (SO16), and functional block diagram. The sole difference is input threshold compatibility: HCT accepts TTL levels (VIH ≥ 2.0 V), while HC requires CMOS levels (VIH ≥ 3.15 V at 4.5 V). Swapping them requires verifying host logic voltage levels but no PCB modification.
