74AHCT1G66GV
Freescale / NXP Semiconductors. Y-IC is a quality distributor of NXP-branded products. We deliver genuine parts, fast service, and reliable support.
Single analog switch (1-gate) with enable, AHCT family (TTL-compatible control). Operates at 5 V systems. Passes analog or digital signals in both directions. Tiny SOT-153 package for space‑constrained designs. Ideal for simple on/off signal gating and isolation. In stock quantity: 4240 units.
Single analog pass switch with enable (E)
Bidirectional signal path (A ↔ B)
AHCT input thresholds (TTL-level compatible control)
Operates from a 5 V supply
High-speed switching and low leakage
Compact 5-pin SOT-153 package
Rail-to-rail signal handling within supply range
High impedance when disabled
Simple, low-cost way to route or gate signals
TTL-compatible control simplifies interfacing with MCU/logic
Small footprint saves PCB space
Low power consumption
Robust performance across typical industrial conditions
Flexible use for both analog and digital small-signal paths
Type: SOT-153 (5-pin, surface-mount)
Material: Molded epoxy package with copper leadframe; lead-free/ROHS options available
Approximate size: About 3.0 mm x 1.6 mm body footprint (industry-standard 5-pin micro SMD)
Pin configuration (typical): VCC, GND, E (enable), A (switch terminal), B (switch terminal)
Thermal characteristics: Designed for low power dissipation; suitable for standard reflow profiles; wide ambient operating range typical of AHCT logic
Electrical properties (overview): 5 V supply operation; TTL-compatible enable input; low on-resistance; low leakage in OFF state; fast switching; bidirectional pass gate behavior
Package / Case code: 591 (vendor case reference as provided)
Current status: Active and widely used. Not near discontinuation based on available vendor guidance.
