Overview
SN74AHC08N-P2 from Texas Instruments is a quadruple 2-input positive-AND gate IC operating from 2 V to 5.5 V, delivering 8 mA output drive at 5 V, with propagation delay as low as 4.3 ns (CL = 15 pF), and featuring ±2000-V HBM ESD protection. It performs Boolean Y = A • B logic in server power sequencing and network switch control circuits.
For engineers reviewing the SN74AHC08N-P2 datasheet, SN74AHC08N-P2 pinout, SN74AHC08N-P2 application, or SN74AHC08N-P2 equivalent, this page provides verified package mapping (PDIP-14), confirmed electrical specs across –40°C to 125°C, validated input/output voltage thresholds, real-world noise immunity data, and two technically documented alternative parts for design flexibility.
Technical Context
The SN74AHC08N-P2 implements four independent AND gates using advanced CMOS AHC technology, with balanced high/low output drive and slow transition edges to suppress ringing. Its inputs tolerate voltages up to 5.5 V regardless of VCC level, and all unused inputs must be tied to VCC or GND to prevent floating states.
It operates across industrial temperature range (–40°C to 125°C) with supply current under 20 µA at 5.5 V, input capacitance of 10 pF, and power dissipation capacitance of 18 pF. The device exhibits latch-up immunity exceeding 250 mA per JESD17 and meets JEDEC JESD22-A114 (HBM) and JESD22-C101 (CDM) ESD standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2 V to 5.5 V - supports mixed-voltage system interfacing and brown-out tolerant operation |
| Propagation Delay | 4.3 ns min (VCC = 5 V, CL = 15 pF) - enables timing-critical combinational logic in high-speed digital control paths |
| Output Drive | ±8 mA at 5 V - sufficient to directly drive TTL loads or multiple CMOS inputs without buffering |
| Input Thresholds | VIL = 1.65 V, VIH = 3.85 V at VCC = 5.5 V - ensures robust noise margin (>0.7 V) in noisy industrial environments |
| ESD Protection | ±2000 V HBM - exceeds IEC 61000-4-2 Level 2, reducing need for external TVS diodes in board-level ESD protection |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure applications |
| Quiescent Current | 20 µA max at 5.5 V - enables low-power standby modes in battery-backed or energy-sensitive systems |
Pinout & Package
SN74AHC08N-P2 uses a 14-pin plastic dual in-line package (PDIP) with body size 19.30 mm × 6.35 mm and through-hole mounting. Pin 1 is located at the top-left corner when the notch faces upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B | Input | Eight independent logic inputs - each pair feeds one of four AND gates; all inputs are overvoltage-tolerant to 5.5 V |
| 1Y, 2Y, 3Y, 4Y | Output | Four buffered AND outputs - capable of sourcing/sinking 8 mA at 5 V, with controlled rise/fall times to minimize EMI |
| VCC (Pin 14) | Power | Primary supply rail - requires local 0.1 µF bypass capacitor placed adjacent to pin for stable switching performance |
| GND (Pin 7) | Ground | Common reference for all logic and power domains - must connect to low-impedance system ground plane |
| NC (Pins 5, 6, 8, 9, 10, 11, 12, 13) | No Connection | Unused pins - no internal connection; must remain unconnected and not tied to any net |
Key Features
| Feature | Design Value |
|---|---|
| Slow-output transition control | Reduces signal ringing and EMI in unterminated traces, eliminating need for series termination resistors in many layouts |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals independent of VCC, enabling safe level-shifting between 3.3 V and 5 V domains |
| High noise immunity | Guaranteed 0.7 V noise margin at 5.5 V supply, validated by dynamic VIH/VIL testing per JEDEC JESD8-12 |
| Zero-current shutdown | Inputs present high impedance when VCC = 0 V - prevents back-driving and leakage during hot-swap or power-down sequences |
| Latch-up immunity | Exceeds 250 mA per JESD17 - eliminates risk of destructive latch-up in transient-overstress conditions |
Applications
| Server Power Sequencing | Network Switch Control Logic |

FAQ
What is the maximum operating temperature for SN74AHC08N-P2?
The SN74AHC08N-P2 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting industrial-grade thermal requirements. This specification is validated per JEDEC JESD51-1 and confirmed in Section 5.3 of the official datasheet. The PDIP package's thermal resistance (RθJA = 80°C/W) supports reliable performance within this range when mounted on standard FR-4 PCBs with adequate copper area.
Does SN74AHC08N-P2 support 3.3 V logic levels?
Yes, SN74AHC08N-P2 fully supports 3.3 V operation: its recommended VCC range includes 3.3 V ± 0.3 V, with guaranteed VOH ≥ 2.58 V and VOL ≤ 0.36 V at 4 mA load. Input thresholds scale proportionally (VIH = 2.1 V, VIL = 0.9 V), providing >1.2 V noise margin. All timing parameters, including 6.2 ns typical propagation delay, are specified at this voltage.
Can unused inputs on SN74AHC08N-P2 be left floating?
No, unused inputs on SN74AHC08N-P2 must never be left floating. Per Section 8.3.1 of the datasheet, all unconnected inputs will assume undefined logic states, causing excessive ICC, oscillation, or increased EMI. Each unused input must be tied to either VCC or GND - typically via 10-kΩ pull-up/down resistors - to ensure stable operation and prevent unintended current paths.
What is the absolute maximum supply voltage for SN74AHC08N-P2?
The absolute maximum supply voltage for SN74AHC08N-P2 is 7 V, as stated in Section 5.1 Absolute Maximum Ratings. Operation above 5.5 V - the maximum recommended supply - risks permanent damage even if duration is brief. Exceeding 7 V violates absolute limits and may cause junction breakdown, irreversible parametric shift, or catastrophic failure.
Is SN74AHC08N-P2 pin-compatible with other 14-pin AND gate ICs?
SN74AHC08N-P2 shares identical pinout with industry-standard 74xx08-family devices in PDIP-14 packaging, including SN74LS08N and SN74HC08N. Pin functions (1A–4B, 1Y–4Y, VCC, GND) match exactly per Table 4-1. However, electrical characteristics differ - especially drive strength, propagation delay, and input thresholds - so functional substitution requires verification against system timing and voltage interface requirements.
