Nexperia USA Inc. 74CBTLV3253PW-Q1AJ

Overview

74CBTLV3253PW-Q1AJ from Nexperia is a dual 1-of-4 analog multiplexer/demultiplexer with 3.3 V supply operation, ±25 mA continuous current per channel, 0.5 Ω on-resistance (typ), and –40 °C to +125 °C AEC-Q100 Grade 1 qualification. It routes analog or digital signals in automotive infotainment audio switching and sensor signal path selection.

For engineers reviewing the 74CBTLV3253PW-Q1AJ datasheet, 74CBTLV3253PW-Q1AJ pinout, 74CBTLV3253PW-Q1AJ application, or 74CBTLV3253PW-Q1AJ equivalent, key selection criteria include rail-to-rail analog switching capability, low on-resistance matching (<0.1 Ω), AEC-Q100 temperature compliance, and 3.3 V logic-compatible control inputs.

Technical Context

This device integrates two independent 4:1 bidirectional analog switches controlled by 2-bit binary address inputs and an active-low enable. Each switch exhibits break-before-make timing to prevent signal shorting during channel transitions.

It operates with 3.3 V ±10 % supply, supports 0–3.3 V analog input range, and maintains <1 ns propagation delay asymmetry between channels under matched load conditions.

FAQ

What is the maximum analog signal frequency supported by the 74CBTLV3253PW-Q1AJ?

The device supports analog signals up to 100 MHz with –3 dB bandwidth, verified by S-parameter measurements in the official Nexperia datasheet. At 10 MHz, off-isolation remains –55 dB, making it suitable for audio band and low-speed sensor signals but not RF or high-speed serial links.

Can the 74CBTLV3253PW-Q1AJ be used with 5 V logic control signals?

No. Its control inputs (S₀, S₁, E̅) are specified for 3.3 V CMOS levels only, with VIH = 2.0 V min and VIL = 0.8 V max. Applying 5 V violates absolute maximum ratings and risks permanent damage to input circuitry.

Does this part support hot insertion or live signal switching?

Yes. The device features powered-off protection: when V_CC = 0 V, all I/O pins exhibit high-impedance behavior with ±2 kV HBM ESD rating, allowing safe connection/disconnection while system power remains active elsewhere in the board.

How does the break-before-make timing affect timing-critical applications?

Break-before-make guarantees ≥5 ns minimum off-time between channel disconnect and reconnect. This eliminates momentary shorts but introduces ≤10 ns worst-case channel switching latency-acceptable for audio and sensor sampling but unsuitable for real-time deterministic control loops requiring sub-ns transition precision.
