Product details
Overview
SN74AHCT367PW from Texas Instruments is a hex buffer and line driver with 3-state outputs, designed for memory address, clock, and bus-oriented driver applications. It features dual 4-line/2-line configuration, TTL-compatible inputs (VIH = 2 V, VIL = 0.8 V), 5-V supply operation, and ±8-mA output drive capability. Used in telecom infrastructure and network switches where controlled bus isolation and voltage translation from 3.3 V to 5 V are required.
For engineers reviewing the SN74AHCT367PW datasheet, SN74AHCT367PW pinout, SN74AHCT367PW application, or SN74AHCT367PW equivalent, this page delivers verified functional modes, switching characteristics (tPLH/tPHL ≤ 8.5 ns at 125°C), thermal metrics (RθJA = 135.9°C/W), ESD robustness (±2000 V HBM/CDM), and precise TSSOP-16 package mapping - all confirmed for SN74AHCT367PW specifically.
Technical Context
The SN74AHCT367PW implements two independent 3-state buffer groups: one with four channels (1A1–1A4 → 1Y1–1Y4) and another with two channels (2A1–2A2 → 2Y1–2Y2), each controlled by active-low enable pins (1OE, 2OE). Its CMOS design ensures balanced output drive and low dynamic power dissipation (Cpd = 22 pF).
It operates across –40°C to +125°C with 4.5 V–5.5 V supply, supports TTL-level input thresholds while being overvoltage tolerant up to 5.5 V, and exhibits slow edge rates (Δt/Δv = 20 ns/V) to minimize output ringing on light-loaded buses - critical for signal integrity in high-density telecom and broadcast equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V logic rails and stable operation under industrial supply variation. |
| IOH/IOL | –8 mA / +8 mA - Sufficient drive strength for fan-out to multiple CMOS/TTL loads without external buffering. |
| tPLH / tPHL | ≤ 8.5 ns (CL = 15 pF, –40°C to 125°C) - Guarantees timing predictability in high-speed address/data bus applications. |
| VIH / VIL | 2.0 V / 0.8 V - Enables direct interfacing with 3.3-V microcontrollers and FPGAs while maintaining TTL compatibility. |
| RθJA | 135.9°C/W (TSSOP-16) - Defines thermal derating limit; requires board-level copper pour or airflow above ~15 mW dissipation. |
| ESD Rating | ±2000 V HBM & CDM - Meets JEDEC JS-001 and JESD22-C101, supporting safe handling in automated assembly lines. |
| ICC (Quiescent) | 40 µA max (–40°C to 125°C) - Enables low-static-power operation in always-on control logic stages. |
Pinout & Package
TSSOP-16 (PW) package: 5.00 mm × 4.40 mm body size, 5 mm × 6.4 mm overall footprint, 0.65 mm lead pitch, 1.2 mm max height. RoHS-compliant, NIPDAU/SN lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low output enables - tie high via pull-up to ensure high-Z during power-up; controls group isolation. |
| 2, 4, 6, 10 | 1A1–1A4 | Noninverting input channels for first 4-bit buffer group - accept TTL/3.3-V logic levels directly. |
| 3, 5, 7, 9 | 1Y1–1Y4 | Corresponding true outputs - high-impedance when 1OE = high; drive 5-V buses with controlled slew. |
| 12, 14 | 2A1, 2A2 | Inputs for second 2-bit buffer group - independently enabled by 2OE; share same VIH/VIL specs. |
| 11, 13 | 2Y1, 2Y2 | True outputs for second group - support separate bus segments or clock distribution paths. |
| 8 | GND | Ground reference - must be low-inductance connection; decoupling capacitor required adjacent to Pin 16. |
| 16 | VCC | 5-V power supply - bypass with 0.1-µF ceramic capacitor placed within 2 mm of pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-voltage compatible inputs | Accepts 0.8-V VIL and 2-V VIH - eliminates level-shifter need when interfacing 3.3-V SoCs to 5-V legacy peripherals. |
| Slow edge rate control | Δt/Δv = 20 ns/V - reduces EMI and overshoot on unterminated traces, critical for compact PCB layouts in set-top boxes. |
| High-impedance state control | Active-low OE with guaranteed high-Z behavior - enables clean bus arbitration and prevents contention in multi-driver systems. |
| Latch-up immunity | >100 mA per JESD78 Class II - ensures robustness against transient ground bounce or supply glitches in industrial environments. |
| Overvoltage-tolerant inputs | Withstand VI up to 5.5 V regardless of VCC - allows hot-swap or mixed-rail debugging without input clamping diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer with 3-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT244PW | Octal (8-channel), identical VCC/VIH/VIL specs, same TSSOP-20 package - higher channel count but larger footprint. | Suitable for full-bus-width buffering (e.g., 8-bit data paths); not pin-compatible due to different pin count and enable architecture (two 4-bit OE groups). | Select SN74AHCT244PW only when expanding from 6- to 8-bit bus width; verify PCB layout change and OE routing compatibility. |
| 74LVC244APW | Lower VCC range (1.65–3.6 V), 3.3-V native logic, 24-mA drive - optimized for modern low-voltage systems, not 5-V tolerant. | Used in battery-powered POS terminals or portable displays; cannot replace SN74AHCT367PW in 5-V legacy interfaces without level shifting. | Choose 74LVC244APW for new 3.3-V designs requiring higher drive; avoid in mixed 5-V/3.3-V systems unless external translation is added. |
Compared with SN74AHCT367PW, SN74AHCT244PW offers more channels in a larger package and different enable grouping, while 74LVC244APW targets lower-voltage domains with no 5-V tolerance - making SN74AHCT367PW uniquely suited for cost-sensitive 5-V bus translation with minimal layout impact.

FAQ
What is the maximum operating temperature for SN74AHCT367PW?
The SN74AHCT367PW is rated for continuous operation from –40°C to +125°C ambient temperature, as specified in Section 5.3 of the official datasheet. This extended range supports deployment in sealed telecom enclosures and industrial control cabinets without forced cooling, provided board-level thermal design respects RθJA = 135.9°C/W.
Does SN74AHCT367PW support 3.3-V input logic levels?
Yes, SN74AHCT367PW explicitly supports 3.3-V input logic: its VIH threshold is 2.0 V minimum and VIL is 0.8 V maximum, allowing direct connection to 3.3-V microcontrollers and FPGAs without level-shifting circuitry - a core feature documented in Section 7.3 and Table 5.3.
Is SN74AHCT367PW pin-compatible with other AHCT-series buffers?
No - SN74AHCT367PW has a unique 16-pin TSSOP pinout defined in Figure 4-1 and Table 4-1. While functionally similar to SN74AHCT244 (octal), it is not pin-compatible due to differing channel count, enable pin placement (1OE/2OE vs. two 4-bit OE groups), and output assignment. Always verify pin mapping before substitution.
What is the recommended bypass capacitor for SN74AHCT367PW?
A 0.1-µF ceramic capacitor is recommended between VCC (Pin 16) and GND (Pin 8), placed within 2 mm of the device per Figure 8-3 layout guidelines. This minimizes high-frequency supply noise and ensures stable switching performance, especially under fast output transitions.
Can SN74AHCT367PW outputs be safely tied together in wired-OR configuration?
No - SN74AHCT367PW outputs are push-pull (totem-pole), not open-drain. Connecting outputs together risks bus contention and exceeds the ±25-mA absolute maximum output current rating. Wired-OR requires explicit open-drain devices or external pull-up resistors with 3-state control - neither supported natively by SN74AHCT367PW.
