Product details
Overview
SN74AHCT367PWR from Texas Instruments is a hex buffer and line driver with 3-state outputs, designed for memory address, clock, and bus-oriented 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. 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 SN74AHCT367PWR datasheet, SN74AHCT367PWR pinout, SN74AHCT367PWR application, or SN74AHCT367PWR 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 ratings (±2000 V HBM/CDM), and precise TSSOP-16 package mapping - all confirmed for the exact SN74AHCT367PWR ordering variant.
Technical Context
The SN74AHCT367PWR implements two independent 3-state buffer groups: one with four channels (1A1–1A4 → 1Y1–1Y4) enabled by active-low 1OE, and another with two channels (2A1–2A2 → 2Y1–2Y2) enabled by active-low 2OE. Each output drives noninverted logic with CMOS-level output swing (VOH ≥ 3.8 V, VOL ≤ 0.44 V at IOL = 8 mA) under 4.5–5.5 V supply.
Its design emphasizes bus integrity: slow edge rates (Δt/Δv ≤ 20 ns/V) minimize ringing, input overvoltage tolerance (VI up to 5.5 V) supports mixed-voltage interfacing, and latch-up immunity (>100 mA per JESD 78 Class II) ensures robustness in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V logic rails and stable operation across industrial temperature range. |
| Input Voltage Thresholds | VIH = 2 V, VIL = 0.8 V - Guarantees reliable recognition of TTL-level signals from legacy or mixed-voltage sources. |
| Output Drive Strength | IOL = 8 mA, IOH = –8 mA - Sufficient for driving moderate capacitive loads (≤50 pF) without external buffering. |
| Propagation Delay | tPLH/tPHL ≤ 8.5 ns (–40°C to 125°C, CL = 15 pF) - Enables use in high-speed address/data bus timing paths up to ~100 MHz. |
| 3-State Enable Timing | tPZH/tPZL ≤ 9 ns (–40°C to 125°C, CL = 15 pF) - Provides fast, predictable bus release for multi-master arbitration. |
| ESD Protection | ±2000 V HBM and CDM - Meets JEDEC standards for handling and board-level reliability without additional protection circuitry. |
| Operating Temperature | –40°C to +125°C - Qualified for extended industrial and telecom infrastructure deployments. |
Pinout & Package
TSSOP-16 package (PW), 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 - optimized for high-density PCB layouts with automated assembly compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low output enable controls for Group 1 (4-channel) and Group 2 (2-channel); must be pulled high via resistor during power-up to ensure high-impedance default state. |
| 2, 4, 6, 10 | 1A1–1A4 | Noninverting input pins for Group 1; accept TTL-compatible logic levels and tolerate up to 5.5 V regardless of VCC. |
| 3, 5, 7, 9 | 1Y1–1Y4 | Corresponding true (noninverting) 3-state outputs for Group 1; high-impedance when 1OE = high. |
| 12, 14 | 2A1, 2A2 | Noninverting inputs for Group 2; functionally identical to Group 1 inputs but with separate enable control. |
| 11, 13 | 2Y1, 2Y2 | True 3-state outputs for Group 2; isolated from Group 1 electrically and timing-wise. |
| 8 | GND | Ground reference for all internal circuitry; requires low-inductance connection to system ground plane. |
| 16 | VCC | 5-V power supply pin; requires local 0.1-µF ceramic bypass capacitor placed adjacent to pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-voltage compatible inputs | Accepts VIH ≥ 2 V and VIL ≤ 0.8 V - enables direct interface with legacy 3.3-V or 5-V TTL logic without level shifters. |
| True (noninverting) outputs | Preserves signal polarity across all six channels - simplifies timing analysis and eliminates need for inversion compensation in bus routing. |
| Controlled edge rates | Δt/Δv ≤ 20 ns/V - reduces EMI and overshoot/undershoot on transmission lines, critical for clean signal integrity in backplane and cable-driven systems. |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - prevents destructive latch-up during transient overvoltage or hot-insertion events. |
| Overvoltage-tolerant inputs | Inputs rated to 5.5 V independent of VCC - allows safe operation when interfacing with higher-voltage peripherals or during power sequencing mismatches. |
Applications

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 |
|---|---|---|---|
| SN74AHCT244PWR | Octal (8-channel) configuration, identical VCC range, timing, and package; no dual-group enable separation. | Requires redesign if independent 4+2 channel control is needed; better suited for full-bus buffering than segmented control. | Select when higher channel count is prioritized over granular enable control. |
| 74LVC244APW,118 | 3.3-V only operation (1.65–3.6 V), lower drive (±24 mA), smaller TSSOP-20 package; lacks TTL input compatibility. | Not suitable for 5-V systems or TTL interfacing; requires level-shifting for legacy signal sources. | Choose only for new 3.3-V designs where lower power and higher density outweigh voltage translation needs. |
Compared with SN74AHCT244PWR and 74LVC244APW,118, the SN74AHCT367PWR uniquely balances dual-group 3-state control, 5-V TTL compatibility, and industrial temperature support - making it optimal for legacy-integrated, thermally demanding bus architectures where enable granularity and voltage translation are essential.

FAQ
What is the maximum operating temperature for SN74AHCT367PWR?
The SN74AHCT367PWR is rated for continuous operation from –40°C to +125°C ambient temperature. This specification is validated per TI's recommended operating conditions and thermal characterization data (RθJA = 135.9°C/W), confirming suitability for enclosed telecom and industrial environments without forced cooling.
Does SN74AHCT367PWR support 3.3-V input signals?
Yes, SN74AHCT367PWR accepts 3.3-V logic inputs reliably: its VIH threshold is 2 V (min) and VIL is 0.8 V (max), ensuring correct recognition of standard 3.3-V CMOS/TTL logic levels. Inputs are also overvoltage tolerant up to 5.5 V, allowing safe interfacing even during power sequencing mismatches.
Can SN74AHCT367PWR replace SN74AHCT244PWR in existing designs?
SN74AHCT367PWR cannot serve as a direct drop-in replacement for SN74AHCT244PWR due to differing channel count (6 vs. 8) and enable architecture (dual 1OE/2OE vs. single OE). While both share pin-compatible TSSOP-16 packages and electrical specs, the SN74AHCT367PWR's grouped enable structure requires schematic and layout revision if substituting into an octal-buffer design.
What is the purpose of the two separate output-enable pins on SN74AHCT367PWR?
The SN74AHCT367PWR uses 1OE (pins 1 and 15) to control four outputs (1Y1–1Y4) and 2OE to control two outputs (2Y1–2Y2), enabling independent bus segmentation. This allows selective isolation of memory address lines versus control/status signals - reducing contention risk and supporting partial bus updates without full system stall.
Is SN74AHCT367PWR RoHS compliant and lead-free?
Yes, SN74AHCT367PWR is RoHS compliant with lead finish NIPDAU | SN and moisture sensitivity level (MSL) rating Level-1 (260°C peak reflow, unlimited floor life). Its packaging meets JEDEC J-STD-020 requirements, and TI confirms full compliance in the official Package Option Addendum dated July 2024.
