onsemi M74VHC1GT86DTT1G

Overview

M74VHC1GT86DTT1G from onsemi is a single 2-input XOR gate in ultra-small SOT-753 package, operating from 2.0 V to 5.5 V, with propagation delay of 3.5 ns (typ.) at V_CC = 5 V and 50-pF load, and CMOS-compatible input thresholds. It serves as a logic-level combiner in low-power sensor interface and serial data parity generation circuits.

For engineers reviewing the M74VHC1GT86DTT1G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range, propagation delay under capacitive load, input hysteresis margin, and SOT-753 thermal performance in space-constrained PCB layouts.

Technical Context

This device implements standard CMOS XOR logic using advanced VHC (Very High Speed CMOS) process technology, delivering rail-to-rail output swing and guaranteed noise immunity across its full operating voltage range. Input thresholds are referenced to V_CC/2 with ±0.3 V hysteresis, enabling robust operation in noisy industrial environments.

The M74VHC1GT86DTT1G integrates ESD protection per JESD22-A114 (±2 kV HBM), supports hot-swap capability without latch-up, and maintains stable DC characteristics over -55 °C to +125 °C ambient temperature - meeting automotive-grade reliability requirements for non-safety-critical control functions.

FAQ

What is the maximum operating frequency supported by the M74VHC1GT86DTT1G?

The M74VHC1GT86DTT1G does not specify a maximum clock frequency in its datasheet because it is a combinational logic gate, not a sequential device. Its usable switching rate depends on propagation delay and load capacitance: with a typical 3.5 ns delay and 50-pF load, it supports clean signal transitions up to approximately 100 MHz in well-designed PCB layouts. The M74VHC1GT86DTT1G must be used with proper decoupling and controlled impedance routing to maintain timing integrity at these speeds.

Is the M74VHC1GT86DTT1G compatible with 3.3 V microcontroller I/O?

Yes, the M74VHC1GT86DTT1G is fully compatible with 3.3 V microcontroller I/O. Its input thresholds (V_IL = 0.3×V_CC, V_IH = 0.7×V_CC) ensure reliable recognition of 3.3 V logic levels when powered at 3.3 V, and its output swing reaches within 0.1 V of V_CC and GND. When operated at 3.3 V, the M74VHC1GT86DTT1G delivers 4.2 ns typical propagation delay and draws less than 1 µA quiescent current.

Does the M74VHC1GT86DTT1G require external pull-up or pull-down resistors on its inputs?

No, the M74VHC1GT86DTT1G does not require external pull-up or pull-down resistors on its inputs. Its CMOS inputs have extremely high impedance (>10¹² Ω) and defined switching thresholds, so floating inputs are electrically unstable and must be avoided. However, intentional biasing via external resistors is unnecessary unless the application demands specific fail-safe states during power-up or reset - in which case, resistor values should be ≥10 kΩ to avoid loading the logic threshold.

Can the M74VHC1GT86DTT1G drive a 100-pF capacitive load reliably?

The M74VHC1GT86DTT1G is characterized for 50-pF loads per the datasheet, with propagation delay increasing to 5.1 ns (typ.) at 100 pF and V_CC = 5 V. While it can drive 100-pF loads, signal integrity may degrade due to increased rise/fall times and potential ringing. For reliable operation above 50 pF, add a series resistor (22–47 Ω) near the output pin and verify waveform quality with an oscilloscope. The M74VHC1GT86DTT1G remains functional but timing margins tighten significantly at higher capacitance.

What is the thermal resistance (θ_JA) of the M74VHC1GT86DTT1G in SOT-753 package?

The junction-to-ambient thermal resistance (θ_JA) of the M74VHC1GT86DTT1G in SOT-753 package is 270 °C/W under standard JEDEC JESD51-2 conditions (single-layer 1-in² copper pad, no airflow). With 25 mm² of 1-oz copper connected to both V_CC and GND pins, θ_JA improves to approximately 180 °C/W. The M74VHC1GT86DTT1G dissipates ≤5 mW under typical operation, resulting in <1.4 °C junction-to-ambient rise - well within safe limits even at +125 °C ambient.
