Nexperia USA Inc. 74CBTLV3257PW-Q1AJ

Overview

74CBTLV3257PW-Q1AJ from Nexperia is a quad 1-of-2 high-speed analog multiplexer/demultiplexer with common select (S) and active-low output enable (OE), operating from 2.3 V to 3.6 V, featuring 5 Ω typical ON-resistance, rail-to-rail signal switching, and IOFF partial power-down protection. It enables bidirectional signal routing in low-voltage digital interconnects, memory address/data bus switching, and FPGA I/O expansion.

For engineers reviewing the 74CBTLV3257PW-Q1AJ datasheet, 74CBTLV3257PW-Q1AJ pinout, 74CBTLV3257PW-Q1AJ application, or 74CBTLV3257PW-Q1AJ equivalent, this device supports high-fidelity signal integrity in automotive infotainment data paths, industrial sensor interface multiplexing, and low-power portable system I/O consolidation where propagation delay <0.25 ns and leakage <±1 μA at 3.6 V are critical.

Technical Context

The 74CBTLV3257PW-Q1AJ implements four independent bilateral analog switches controlled by a shared S input and globally enabled/disabled via OE. Each switch exhibits CMOS-compatible logic thresholds with Schmitt-trigger inputs for noise immunity across the full 2.3–3.6 V supply range.

Its IOFF circuitry ensures sub-10 μA power-off leakage when VCC = 0 V, enabling hot-swap capability and safe operation during partial power-down sequences. The device maintains rail-to-rail voltage handling on all data I/O pins (1A–4A, 1B1–4B2) without level-shifting requirements.

FAQ

What is the maximum allowable signal voltage swing on the 74CBTLV3257PW-Q1AJ I/O pins?

The device supports rail-to-rail switching: signals may swing from GND to VCC (0 V to 3.6 V) on all data I/O pins (1A–4A, 1B1–4B2) without damage or performance degradation, provided VSW remains within −0.5 V to VCC + 0.5 V per absolute maximum ratings.

How does the IOFF feature behave during power-down sequences?

When VCC drops to 0 V, the IOFF circuitry actively disables all switch paths, limiting leakage current to ±50 μA maximum regardless of voltage applied to any I/O pin-preventing backflow current that could disrupt upstream sensors or downstream ADC references during brown-out conditions.

Can the 74CBTLV3257PW-Q1AJ be used with 1.8 V control logic?

No-its control inputs (S and OE) require VIH ≥ 2.0 V at VCC = 2.7–3.6 V and ≥1.7 V at VCC = 2.3–2.7 V per JESD8-5/JESD8-B compliance; 1.8 V logic may not reliably assert HIGH states, risking undefined switching behavior.

Is there a recommended pull-up resistor value for OE when tied to VCC?

Yes-OE should connect to VCC via a pull-up resistor sized to limit current to ≤100 μA when driven LOW; for VCC = 3.3 V, a 33 kΩ resistor satisfies this while ensuring fast disable timing and compatibility with standard GPIO drive strength.
