onsemi MC74VHC1GT86DBVT1G

Overview

MC74VHC1GT86DBVT1G from onsemi is a single 2-input XOR gate in ultra-small SC-70-5 (SOT-353) package, operating from 2.0 V to 5.5 V supply, with propagation delay of 3.5 ns (at V_CC = 5 V), CMOS-level input thresholds, and rail-to-rail output swing - used for logic-level signal inversion, parity generation, and digital waveform mixing in space-constrained portable interfaces.

For engineers reviewing the MC74VHC1GT86DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility, propagation delay budget, input hysteresis absence, SC-70 footprint constraints, and TTL/CMOS mixed-signal interfacing requirements.

Technical Context

This device implements standard CMOS XOR logic using a complementary transistor pair architecture with no internal Schmitt-trigger input conditioning. It supports true 2.0–5.5 V operation without level-shifting circuitry and delivers symmetrical rise/fall times under capacitive loads ≤ 50 pF.

The MC74VHC1GT86DBVT1G integrates ESD protection per HBM ≥ 2 kV and operates across –55 °C to +125 °C ambient temperature, meeting industrial-grade reliability without requiring external biasing or pull-up resistors for standard logic interfacing.

FAQ

What is the maximum operating frequency supported by the MC74VHC1GT86DBVT1G?

The MC74VHC1GT86DBVT1G does not specify a maximum clock frequency in its datasheet because it is a combinational logic gate, not a sequential device. Its usable toggle rate is determined by propagation delay: at V_CC = 5 V and C_L = 50 pF, t_PD = 3.5 ns, enabling reliable operation up to ~140 MHz in non-critical timing paths. For synchronous designs, system-level setup/hold margins must be verified independently. The MC74VHC1GT86DBVT1G remains stable across its full –55 °C to +125 °C temperature range.

Can the MC74VHC1GT86DBVT1G operate with a 1.8 V supply?

No, the MC74VHC1GT86DBVT1G has a specified minimum supply voltage of 2.0 V and is not guaranteed to function correctly below that level. At 1.8 V, input thresholds become undefined and output drive capability degrades significantly. For 1.8 V systems, consider alternatives such as the SN74LVC1G86DBVR (1.65–5.5 V range) or 74AUP1G86GW,125 (0.8–3.6 V). The MC74VHC1GT86DBVT1G must be powered within its validated 2.0–5.5 V window to meet datasheet performance.

Is the MC74VHC1GT86DBVT1G pin-compatible with other SC-70-5 logic gates?

Yes, the MC74VHC1GT86DBVT1G uses the standard SC-70-5 (SOT-353) pinout: Pin 1 = A, Pin 2 = B, Pin 3 = GND, Pin 4 = Y, Pin 5 = V_CC. This matches industry-standard assignments for single-gate logic devices in this package, including SN74LVC1G86DBVR and 74AUP1G86GW,125. However, electrical behavior (e.g., drive strength, propagation delay, supply range) differs between families, so substitution requires validation of timing and voltage compatibility. The MC74VHC1GT86DBVT1G maintains this mechanical and pinout consistency while delivering optimized 5 V performance.

Does the MC74VHC1GT86DBVT1G include Schmitt-trigger inputs?

No, the MC74VHC1GT86DBVT1G features standard CMOS input thresholds (V_IL = 0.3×V_CC, V_IH = 0.7×V_CC) without hysteresis. It is not a Schmitt-trigger device, meaning it lacks built-in noise immunity enhancement for slow-rising or noisy input signals. For applications with marginal edge rates or high EMI, external RC filtering or a dedicated Schmitt-trigger gate (e.g., MC74VHC1GT14DBVT1G) should be used upstream. The MC74VHC1GT86DBVT1G relies on clean, monotonic input transitions for deterministic operation.

What is the ESD rating of the MC74VHC1GT86DBVT1G?

The MC74VHC1GT86DBVT1G is rated for Human Body Model (HBM) ESD protection ≥ 2 kV per JESD22-A114, verified during qualification testing. It does not specify Machine Model (MM) or Charged Device Model (CDM) ratings in the public datasheet. Standard handling precautions - including grounded workstations, anti-static packaging, and ionized air - are recommended during assembly. This ESD robustness supports reliable deployment in industrial environments where transient coupling may occur. The MC74VHC1GT86DBVT1G meets typical board-level ESD immunity requirements without requiring additional protection components in most use cases.
