Product details
Overview
MC74ACT86D from onsemi is a quad 2-input exclusive-OR gate in SOIC-14 package, designed for high-speed digital logic applications requiring TTL-compatible inputs and CMOS outputs. It operates at 4.5 V to 5.5 V supply, delivers ±24 mA output drive, exhibits 7.0–10.5 ns propagation delay (tPHL/tPLH) at 5.0 V/50 pF, and supports industrial temperature range (−40°C to +85°C). It is used in arithmetic logic units, parity generators, and data comparators.
For engineers reviewing the MC74ACT86D datasheet, pinout, applications, or equivalent options, key selection considerations include its ACT-series TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V @ 5 V), guaranteed 24 mA output sink/source capability, SOIC-14 Pb-free packaging, and verified performance across −40°C to +85°C ambient conditions.
Technical Context
The MC74ACT86D implements four independent XOR logic functions using high-performance silicon-gate CMOS technology. Each gate accepts TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 5.0 V) and drives CMOS-compatible loads with rail-to-rail output swing and ±24 mA current capability.
Its AC characteristics are specified at CL = 50 pF and VCC = 5.0 V ±0.5 V, with typical tPHL = 7.0 ns and tPLH = 8.5 ns at +25°C. DC parameters include VOH ≥ 4.4 V (IOH = −24 mA) and VOL ≤ 0.44 V (IOL = 24 mA), ensuring robust noise margins in mixed-signal systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT86DR | Identical logic function, pinout, and DC/AC specs; TI-manufactured, same SOIC-14 package | No functional deviation - validated drop-in replacement per TI datasheet SN74ACT86 | Select when dual-sourcing or TI-aligned BOM requirements apply |
| 74VHC86M | Higher VCC range (2.0–5.5 V), lower drive (±8 mA), slower max delay (13 ns @ 5 V) | Acceptable for low-power, non-critical timing applications but not for 24 mA load or <11 ns timing paths | Choose only if supply voltage flexibility below 4.5 V is required and drive strength is secondary |
Compared with MC74ACT86D, SN74ACT86DR offers identical electrical and mechanical compatibility for seamless second-source procurement, while 74VHC86M trades drive strength and speed for wider supply range - making MC74ACT86D optimal for industrial 5 V systems demanding robust output drive and tight timing control.

FAQ
What logic family does the MC74ACT86D belong to, and how does it differ from standard 74AC devices?
The MC74ACT86D belongs to the 74ACT (Advanced CMOS TTL-compatible) family. Unlike 74AC devices, which have CMOS input thresholds (VIH ≈ 3.5 V at 5 V), the MC74ACT86D features TTL-compatible inputs (VIH = 2.0 V, VIL = 0.8 V at VCC = 5.0 V), enabling direct interface with 74LS and other bipolar logic without level shifters. Its output drive (±24 mA) and propagation delay (≤10.5 ns) are also optimized for 5 V systems, distinguishing it from the broader 74AC series.
Can the MC74ACT86D operate reliably at 3.3 V supply voltage?
No - the MC74ACT86D is not rated for 3.3 V operation. Its recommended operating VCC range is strictly 4.5 V to 5.5 V, as confirmed by the "RECOMMENDED OPERATING CONDITIONS" table in the datasheet. At 3.3 V, input thresholds (VIH/VIL) and output drive specifications are not guaranteed, and functionality cannot be assured. For 3.3 V systems, consider 74LVC86 or 74AHC86 instead.
What is the maximum capacitive load the MC74ACT86D can drive while maintaining specified propagation delay?
The MC74ACT86D's AC characteristics - including tPLH and tPHL - are specified at CL = 50 pF, as stated in the "AC CHARACTERISTICS" table. Driving loads significantly above 50 pF will increase propagation delay nonlinearly and may degrade waveform integrity. For loads exceeding 50 pF, buffer stages or layout optimization (shorter traces, reduced stubs) are recommended to maintain timing compliance in the MC74ACT86D application.
Does the MC74ACT86D support hot insertion or live insertion into a powered backplane?
No - the MC74ACT86D is not designed for hot insertion. Its absolute maximum ratings do not include live-insertion stress conditions, and the absence of bus-hold, power-up 3-state, or Ioff protection means uncontrolled current flow and potential latch-up may occur during partial powering. Always power-cycle the system before inserting or removing the MC74ACT86D.
Is the MC74ACT86D pin-compatible with the older 74LS86 or 74F86 logic devices?
Yes - the MC74ACT86D uses the industry-standard 14-pin SOIC footprint and identical pinout (per Figure 1 in the datasheet) as 74LS86 and 74F86. All four XOR gates, power, and ground pins align exactly. However, due to higher output drive and faster switching, ensure PCB trace inductance and load capacitance are reviewed to avoid ringing or ground bounce not present in the older bipolar parts.
