NXP Semiconductors 74HC4353D,652

Overview

74HC4353D,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 Ω typical ON-resistance at 9 V supply, and dual enable inputs (E1 active LOW, E2 active HIGH) for independent channel control. It is used in precision analog data acquisition systems requiring channel selection with latch hold functionality.

For engineers reviewing the 74HC4353D,652 datasheet, 74HC4353D,652 pinout, 74HC4353D,652 application, or 74HC4353D,652 equivalent, key selection criteria include guaranteed 2.0–10.0 V VCC−VEE operation, break-before-make switching behavior, latch-enable transparency timing (tW ≥ 16 ns), and switch capacitance (CS = 5 pF independent, 8 pF common) critical for high-fidelity signal integrity.

Technical Context

The 74HC4353D,652 implements three independent analog switch pairs-each with two bidirectional Y terminals (nY0/nY1) and one shared Z terminal (nZ)-controlled by three select lines (S1–S3) and latched via active-LOW LE. Digital control logic operates from VCC/GND (2.0–10.0 V), while analog paths swing between VCC (positive rail) and VEE (negative rail), supporting true bipolar ±5 V signal handling when VEE = −5 V.

Its CMOS Si-gate architecture delivers low charge injection (<1 pC typical), minimal crosstalk (−60 dB at 1 MHz), and high off-isolation (−50 dB feed-through). The device complies with JEDEC standard no. 7A and supports both analog and digital multiplexing modes-VEE tied to GND enables pure digital use, while VEE < 0 V enables full analog rail-to-rail operation.

FAQ

What is the maximum allowable VCC−VEE voltage for 74HC4353D,652?

The absolute maximum VCC−VEE rating for 74HC4353D,652 is 10.0 V, as specified in the "Ratings" section. Operation beyond this risks permanent damage to the internal analog switches. For reliable ±5 V analog signal handling, configure VCC = +5 V and VEE = −5 V, resulting in exactly 10.0 V differential-within the safe operating area shown in Figure 6 of the datasheet.

Can 74HC4353D,652 operate with VEE tied to GND?

Yes, 74HC4353D,652 can operate with VEE = GND for digital multiplexing applications. In this configuration, the analog I/Os (nY0/nY1/nZ) swing from GND to VCC, supporting unipolar digital signal routing. The device retains full functionality-including latch enable and dual enable logic-but loses bipolar analog capability and maximum ON-resistance degrades slightly below 2.0 V VCC.

How does the latch enable (LE) function affect timing in 74HC4353D,652?

The LE input controls transparency vs. latched operation: when LE is HIGH, S1–S3 changes immediately affect channel selection; on the HIGH-to-LOW transition of LE, the current S1–S3 state is captured and held regardless of subsequent select-line changes. Minimum LE pulse width is 16 ns (typical at VCC = 4.5 V), ensuring reliable capture without metastability in synchronous control systems using 74HC4353D,652.

What is the significance of "break-before-make" in 74HC4353D,652?

"Break-before-make" means that during channel switching (e.g., from nY0–nZ to nY1–nZ), the first switch opens completely before the second closes. This prevents momentary short-circuiting between nY0 and nY1-a critical safeguard when routing signals from different voltage domains or high-impedance sources. The behavior is inherent to the 74HC4353D,652's internal switch architecture and requires no external timing control.

Is 74HC4353D,652 compatible with 3.3 V digital control logic?

Yes, 74HC4353D,652 supports 3.3 V digital control when VCC = 3.3 V, as its HC logic family specifies VCC min = 2.0 V. Input thresholds scale with VCC: VIH ≈ 0.7×VCC (2.3 V at 3.3 V), making it compatible with standard 3.3 V CMOS outputs. However, analog performance (e.g., RON, fmax) is reduced versus 5 V operation-verify against your signal fidelity requirements using the datasheet's 3.3 V characterization curves.
