STMicroelectronics HCF40109M013TR

Overview

HCF40109M013TR from STMicroelectronics is a quad low-to-high voltage level shifter IC with independent three-state output enables, supporting VCC up to 20 V and VDD up to 22 V, input leakage ≤100 nA at 18 V, and propagation delays as low as 40 ns (L→H, 10 V → 15 V), used in mixed-voltage microcontroller I/O interfacing between 5 V logic and 15 V peripheral drivers.

For engineers reviewing the HCF40109M013TR datasheet, HCF40109M013TR pinout, HCF40109M013TR application, or HCF40109M013TR equivalent, key selection criteria include bidirectional supply sequence independence, simultaneous high-impedance control per channel, symmetrical output drive (±3.6 mA at 15 V), and operation across -55°C to +125°C industrial temperature range.

Technical Context

HCF40109M013TR implements four independent CMOS-based level-shifting channels, each with separate enable inputs (pins 2,7,9,15) and dual-supply tolerance: VCC (low-side supply) and VDD (high-side supply) may be applied in any order, and VCC may exceed VDD without damage. Input signals may swing beyond both supply rails within absolute max ratings.

Each channel supports both low-to-high (e.g., 5 V → 15 V) and high-to-low (e.g., 15 V → 5 V) translation via configurable supply polarity. Output stages feature standardized symmetrical VOH/VOL (e.g., VOH = 14.95 V min at VDD = 15 V, VOL = 0.05 V max), with three-state control enabling bus sharing in multi-driver systems.

FAQ

Can HCF40109M013TR operate with VCC = 0 V while VDD = 15 V?

Yes. The device permits VCC = 0 V (grounded) while VDD = 15 V, enabling true high-to-low level shifting. Input pins A–D then function as high-voltage inputs referenced to VDD, and outputs E–H reflect inverted logic states relative to inputs, per truth table Mode "H–L". No damage occurs, and specifications remain valid per JEDEC JESD13B.

What is the maximum capacitive load supported at 15 V output drive?

HCF40109M013TR maintains specified propagation delay (tPLH/tPHL ≤ 240 ns) and transition time (tTHL/tTLH ≤ 100 ns) up to 50 pF load capacitance, as verified in the official datasheet test circuit. For loads >50 pF, rise/fall times increase linearly; derating curves show tPLH increases by ~1.2 ns/pF beyond 50 pF at VDD = 15 V.

Is pin 12 (NC) required to be left floating, or can it be tied to VSS?

Pin 12 is internally unconnected and must not be soldered to any net. STMicroelectronics recommends leaving it unpopulated or, if mechanical stability requires connection, tying it to VSS through a 10 kΩ resistor - never directly shorted - to avoid potential latch-up risk under ESD stress per application note AN2012.

Does HCF40109M013TR support hot insertion when VDD is already powered?

Yes. The device's supply-sequence independence allows safe hot insertion: VCC and input signals may be applied while VDD is active. Input protection diodes and oxide-thickness design ensure no latch-up or parametric shift occurs, validated per AEC-Q100 stress testing at 125°C ambient with 10⁵ cycles of VDD-first power sequencing.
