Product details

Overview

MC74AC11DR2 from onsemi is a triple 3-input AND gate in high-performance silicon-gate CMOS technology, operating at supply voltages from 2.0 V to 6.0 V, delivering ±24 mA output drive, with propagation delays as low as 4.0 ns (typ) at 5.0 V, and used in digital logic control, address decoding, and enable gating in industrial microcontroller peripherals.

For engineers reviewing the MC74AC11DR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, SOIC-14 package mapping, real-world use cases, and validated alternative parts for logic-level compatibility and supply voltage range alignment.

Technical Context

The MC74AC11DR2 implements three independent 3-input AND functions using CMOS transistor pairs with rail-to-rail input thresholds and buffered outputs. It supports operation across −40°C to +85°C ambient temperature and maintains guaranteed VIH/VIL levels at 2.1 V/0.9 V (VCC = 3.0 V) and 3.85 V/1.65 V (VCC = 5.5 V).

Its AC performance is characterized at CL = 50 pF, with tPLH/tPHL max of 8.0 ns and 7.5 ns respectively at VCC = 5.0 V and TA = −40°C to +85°C. Input capacitance is 4.5 pF and power dissipation capacitance is 20 pF, enabling predictable timing in synchronous logic interfaces.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple 3-input AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AC11DR	Same logic function, identical SOIC-14 package, but TI-specified VOH/VOL limits differ slightly at 3.3 V (VOH min = 2.9 V vs. onsemi's 2.9 V at VCC = 3.0 V)	Valid for 3.3 V systems where TI's characterization methodology aligns with existing validation data	Select when sourcing from TI-distributed channels or when matching legacy TI-based BOMs
74VHC11M	Higher VCC max (7 V), lower ICC (1 µA typ), but slower max propagation delay (10.5 ns at 5 V) and no guaranteed 24 mA drive	Suitable for battery-powered systems prioritizing quiescent current over speed	Prefer when ultra-low standby power is critical and timing budget allows ≥10 ns delay margin

Compared with SN74AC11DR and 74VHC11M, the MC74AC11DR2 offers superior output drive (±24 mA) and tighter propagation delay consistency across temperature, making it optimal for industrial control interfaces requiring robust fanout and deterministic timing.

FAQ

What logic family does MC74AC11DR2 belong to, and how does it differ from 74ACT variants?

The MC74AC11DR2 belongs to the 74AC (Advanced CMOS) logic family, optimized for high speed and low power across 2.0–6.0 V operation. Unlike the 74ACT variant (e.g., MC74ACT11DR2G), it uses CMOS-compatible input thresholds-not TTL-compatible-so VIH is referenced to VCC (e.g., 3.85 V at 5.5 V), not fixed 2.0 V. This makes MC74AC11DR2 ideal for mixed-voltage systems where inputs swing rail-to-rail, whereas 74ACT variants interface directly with legacy TTL outputs. Both share the same SOIC-14 package and ±24 mA drive capability.

Can MC74AC11DR2 operate reliably at 3.3 V, and what are its key DC parameters at that voltage?

Yes, MC74AC11DR2 is fully specified for 3.3 V operation (VCC = 3.0 V to 3.6 V per recommended ranges). At VCC = 3.0 V, it guarantees VIH ≥ 2.1 V, VIL ≤ 0.9 V, VOH ≥ 2.9 V (at −50 µA), VOL ≤ 0.1 V (at 50 µA), and output drive of ±24 mA. Propagation delay is max 9.5 ns (tPLH) and 9.5 ns (tPHL) at TA = −40°C to +85°C and CL = 50 pF. These values ensure robust noise margin (>1.2 V) and compatibility with 3.3 V LVTTL and LVCMOS interfaces.

Is MC74AC11DR2 pin-compatible with other triple 3-input AND gates like SN74AC11DR or 74VHC11?

Yes, MC74AC11DR2 is pin-compatible with SN74AC11DR (TI) and 74VHC11 (Toshiba, NXP) in SOIC-14 packages: all follow identical 14-pin assignment (GND at 7, VCC at 12, Y1–Y3 at pins 3/14/11, and inputs distributed across remaining pins). However, absolute maximum ratings and AC timing differ-e.g., 74VHC11 has higher VCC max (7 V) but slower propagation (10.5 ns), while SN74AC11DR matches timing closely but specifies slightly different VOH/VOL limits at 3.3 V. Electrical substitution requires verification of load, speed, and voltage margin requirements for MC74AC11DR2.

Does MC74AC11DR2 support hot insertion or partial power-down scenarios?

MC74AC11DR2 supports limited hot-insertion resilience due to its rail-to-rail input voltage rating (VI = −0.5 V to VCC + 0.5 V) and guaranteed latch-up immunity (±100 mA at 85°C per EIA/JESD78). However, it is not explicitly characterized for live-insertion protocols. For safe partial power-down, ensure VCC is stable before applying inputs, and avoid floating inputs-tie unused inputs to VCC or GND. The device's CMOS inputs draw <±1.0 µA leakage (VI = VCC/GND), minimizing contention current during transitional states. Always refer to the MC74AC11DR2 datasheet section "DC Input Diode Current" for absolute max handling.

What is the thermal performance of MC74AC11DR2 in SOIC-14, and how should it be managed in high-density layouts?

MC74AC11DR2 in SOIC-14 (Case 751A) has a junction-to-ambient thermal resistance (θJA) of 116°C/W in still air at 25°C, with max power dissipation of 1077 mW. Under typical operation (e.g., 10 MHz toggle, CL = 50 pF), dynamic power is ~1.5 mW per gate (P = CPD × VCC² × f = 20 pF × 25 V² × 10⁷ Hz ≈ 0.5 mW), so thermal rise is negligible. In high-density layouts, maintain ≥0.5 mm clearance around the package, avoid copper pours under the body, and use 2–4 thermal vias connected to inner ground planes if ambient exceeds 70°C. No heatsink is required for standard industrial use.
