STMicroelectronics HCF4051YM013TR

Overview

HCF4051YM013TR from STMicroelectronics is a single 8-channel analog multiplexer/demultiplexer in SO-16 package, operating over -40 °C to +125 °C with VDD–VSS supply range of 3–20 V and VDD–VEE up to 18 V. It features 125 Ω typical ON-resistance, ±100 pA typical OFF-leakage at 18 V, and <0.5% distortion at 1 kHz, enabling precise signal routing in automotive sensor interfaces and industrial data acquisition systems.

For engineers reviewing the HCF4051YM013TR datasheet, HCF4051YM013TR pinout, HCF4051YM013TR application, or HCF4051YM013TR equivalent, key selection criteria include its AEC-Q100 qualified automotive grade, matched RON (5 Ω typ. at 15 V), quiescent current ≤600 μA at 15 V, and 20 V peak-to-peak analog signal handling capability across full temperature range.

Technical Context

The HCF4051YM013TR implements a CMOS transmission-gate-based 8:1 analog switch architecture with on-chip binary decoder and active-low inhibit control. Its three address inputs (A, B, C) select one of eight bidirectional channels between common I/O (pin 3) and independent channel terminals (pins 1, 2, 4, 5, 12, 13, 14, 15), while INH (pin 6) disables all paths simultaneously.

It supports dual-supply operation with independent VDD (pin 16), VSS (pin 8), and VEE (pin 7) rails, allowing analog signals to swing from VEE to VDD - up to 20 V p-p - while digital control remains referenced to VDD/VSS. Propagation delays are 120–240 ns (address-to-output, 15 V), and crosstalk is ≤3 MHz at -40 dB.

FAQ

What is the maximum analog signal voltage range supported by the HCF4051YM013TR?

The HCF4051YM013TR supports analog signals from VEE to VDD, with absolute maximum ratings of -0.5 V to +22 V on VDD and VEE pins. At VDD–VEE = 18 V, it handles up to 20 V peak-to-peak signals. For example, with VDD = +5 V, VSS = 0 V, and VEE = -13.5 V, analog swing is -13.5 V to +4.5 V - confirmed in Section 9 of the datasheet.

Does the HCF4051YM013TR require external level shifting for 5 V logic control when using ±12 V analog supplies?

No. The device uses VSS as the digital ground reference, and address/inhibit inputs operate with VIH = 3.5 V (min.) and VIL = 1.5 V (max.) at VDD = 5 V. With VDD = 5 V and VSS = 0 V, standard 5 V TTL/CMOS logic directly controls the switch - even when VEE = -12 V and VDD = +5 V - because digital inputs are referenced only to VSS, not VEE.

How does the inhibit (INH) function interact with channel selection timing?

The INH pin overrides address inputs asynchronously: when INH = high, all channels disconnect immediately regardless of A/B/C state. Propagation delay from INH high-to-OFF is 70–160 ns (depending on supply), and from INH low-to-ON is 120–240 ns at VDD = 15 V - specified in Table 7 under "Propagation delay: inhibit to signal OUT".

Is the HCF4051YM013TR pin-compatible with the standard HCF4051M013TR?

Yes. Both share identical SO-16 footprint, pinout, and electrical specifications. The "Y" suffix denotes AEC-Q100 qualification and extended -40/+125 °C temperature range (vs. -55/+125 °C for M013TR), but mechanical and functional compatibility is maintained - confirmed in Table 1 and Table 10 of the datasheet.
