STMicroelectronics HCF4097M013TR

Overview

HCF4097M013TR from STMicroelectronics is a CMOS analog differential 8-channel multiplexer/demultiplexer with internal binary address decoding, 125Ω typical ON resistance at VDD–VSS = 15V, 10pA typical OFF channel leakage at 10V, and ±100nA max input leakage at VDD = 18V. It supports dual-channel (X/Y) signal routing in precision data acquisition systems requiring matched switch characteristics (∆RON = 5Ω typ.) and low quiescent power (0.2µW typ. at 10V).

For engineers reviewing the HCF4097M013TR datasheet, HCF4097M013TR pinout, HCF4097M013TR application, or HCF4097M013TR equivalent, key selection criteria include differential channel matching, wide supply range (3–20V), symmetrical output behavior, low feedthrough (0.2mV), and guaranteed operation from –55°C to +125°C in industrial instrumentation.

Technical Context

The HCF4097M013TR implements a dual-bank 8:1 analog multiplexer architecture with three binary address inputs (A/B/C) and an active-high inhibit control, enabling selection of one of eight differential X/Y channel pairs. Its transmission-gate-based switches deliver voltage-independent RON over full signal swing (±7.5V at 15V supply) and exhibit matched ∆RON ≤ 5Ω across channels.

It operates across 3–20V supply rails with specified static and dynamic performance up to 125°C, including –40dB feedthrough suppression at 12MHz (common out/in), <1MHz crosstalk isolation between sections, and propagation delays as low as 65ns (address-to-output ON) at VDD = 15V with CL = 50pF.

FAQ

What is the maximum signal voltage swing supported by HCF4097M013TR?

The device supports ±7.5V p-p signal swing when operated at VDD–VSS = 15V, with full rail-to-rail conduction and symmetrical ON resistance. At 20V supply, the usable analog range extends to ±10V p-p, limited only by absolute maximum ratings (VI = –0.5V to VDD + 0.5V). Exceeding these bounds risks latch-up or permanent damage.

Does HCF4097M013TR require external pull-up or pull-down resistors on address lines?

No. The A, B, C, and INH inputs have CMOS-compatible thresholds with guaranteed VIH ≥ 70% VDD and VIL ≤ 30% VDD across temperature and supply. Internal input protection diodes and defined logic states eliminate need for external biasing - provided VDD is stable and noise on control lines remains below 0.5Vpp.

How does the inhibit function interact with channel switching timing?

When INH transitions high, all channels turn OFF within 130ns (max) at VDD = 15V. During turn-OFF, a momentary conductive path to VSS dumps charge from capacitive loads - causing ~3–4% voltage loss on a 100pF node. No such discharge occurs during turn-ON; instead, a 65mV capacitive coupling spike appears on the channel due to inhibit-to-channel coupling.

Can HCF4097M013TR be used in bidirectional signal paths with different supply domains?

Yes - its transmission-gate structure supports true bidirectional analog signal flow. However, if VDD and signal sources use separate supplies, VDD current capability must exceed VDD/RL to prevent clamp action. Also, ensure all signal voltages remain within –0.5V to VDD + 0.5V relative to VSS to avoid forward-biasing internal protection diodes.
