Product details
Overview
SN74AHCT367PWG4 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 for level translation and bus isolation.
For engineers reviewing the SN74AHCT367PWG4 datasheet, SN74AHCT367PWG4 pinout, SN74AHCT367PWG4 application, or SN74AHCT367PWG4 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 against TI's July 2024 production data sheet SCLS418I.
Technical Context
The SN74AHCT367PWG4 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 swing referenced to VCC.
Its design targets low-noise bus interfacing: slow edge rates (Δt/Δv ≤ 20 ns/V) minimize ringing, input overvoltage tolerance (up to 5.5 V) supports mixed-voltage systems, and latch-up immunity (>100 mA per JESD 78 Class II) ensures robustness in industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 4.5 V to 5.5 V - ensures compatibility with standard 5-V logic rails and stable operation across industrial temperature range. |
| VOH / VOL | ≥3.8 V @ –8 mA / ≤0.44 V @ 8 mA - guarantees TTL- and CMOS-compatible output levels under full load. |
| tPLH / tPHL | ≤8.5 ns @ CL = 15 pF, –40°C to 125°C - enables reliable timing in high-speed address/data buses up to ~100 MHz. |
| IOZ Off-State Current | ±2.5 µA max - maintains true high-impedance state during bus contention or power sequencing. |
| ESD Rating | ±2000 V HBM & CDM - meets JEDEC standards for handling without special ESD controls in assembly. |
| Operating Temp | –40°C to 125°C - qualified for extended industrial and telecom infrastructure deployments. |
| Input Compatibility | TTL voltage thresholds (VIH = 2 V, VIL = 0.8 V) - allows direct interface with legacy 3.3-V and 5-V microcontrollers and FPGAs. |
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, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low output enable controls group isolation; tie to VCC via pull-up for safe power-up high-Z state. |
| 2, 4, 6, 10 | 1A1–1A4, 2A1–2A2 | CMOS/TTL-compatible digital inputs; accept 0–5.5 V, tolerate floating only if externally biased. |
| 3, 5, 7, 9, 11, 13 | 1Y1–1Y4, 2Y1–2Y2 | Noninverting 3-state outputs; drive ±8 mA, support bus sharing with other drivers. |
| 8 | GND | Ground reference for all I/O and internal logic; requires low-impedance PCB plane connection. |
| 16 | VCC | 5-V power supply; bypass with 0.1-µF capacitor near pin to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Accepts 0.8-V low and 2-V high thresholds - eliminates need for external level shifters when interfacing 3.3-V logic to 5-V buses. |
| Slow edge rate control | Δt/Δv ≤ 20 ns/V - reduces EMI and signal integrity issues on unterminated traces in telecom and set-top box designs. |
| High-impedance output state | IOZ ≤ ±2.5 µA - prevents bus contention and leakage current accumulation in multi-driver systems like memory address lines. |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - ensures survivability during transient overcurrent events in industrial power-up sequences. |
| Overvoltage-tolerant inputs | VI up to 5.5 V regardless of VCC - enables hot-swap capability and mixed-supply system integration without 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 |
|---|---|---|---|
| SN74AHCT244PWR | Octal (8-channel) configuration, identical VCC range, VOH/VOL, and timing specs; same TSSOP-20 package. | Higher channel count suits wider data buses; not pin-compatible due to different pin count and layout. | Select when expanding bus width beyond six lines or requiring matched timing across eight channels. |
| 74LVC244APW,118 | 3.3-V only supply (1.65–3.6 V), lower drive (±24 mA), faster propagation (tPD ≈ 3.2 ns), smaller TSSOP-20 package. | Optimized for low-voltage, high-speed digital systems; lacks 5-V tolerance and TTL input compatibility. | Choose for battery-powered or FPGA-adjacent applications where 3.3-V native operation and minimal propagation delay are critical. |
Compared with SN74AHCT367PWG4, SN74AHCT244PWR offers more channels but requires PCB redesign, while 74LVC244APW,118 delivers speed and efficiency at the cost of 5-V interoperability - making SN74AHCT367PWG4 the optimal choice for legacy 5-V bus isolation with TTL compatibility.

FAQ
What is the maximum operating temperature for SN74AHCT367PWG4?
The SN74AHCT367PWG4 is rated for continuous operation from –40°C to +125°C ambient temperature, as specified in Section 5.3 of the TI SCLS418I datasheet. This rating applies to all active packages including the PW (TSSOP-16) variant, and is validated across electrical parameters including VOH, VOL, and tPLH/tPHL. Thermal derating is not required within this range when used with recommended PCB copper area and airflow.
Does SN74AHCT367PWG4 support 3.3-V input logic levels?
Yes, SN74AHCT367PWG4 supports 3.3-V input logic levels directly: its VIH threshold is 2.0 V min and VIL is 0.8 V max at VCC = 4.5–5.5 V, ensuring reliable recognition of 3.3-V high/low signals without external level shifting. This makes SN74AHCT367PWG4 ideal for translating between 3.3-V microcontrollers and 5-V bus systems, as confirmed in Section 7.3 Feature Description and Figure 8-2 of the datasheet.
What is the output drive strength of SN74AHCT367PWG4?
The SN74AHCT367PWG4 provides ±8 mA output drive per channel at VCC = 4.5–5.5 V, as specified in Section 5.3 Recommended Operating Conditions. It can sustain ±25 mA absolute maximum per output (Section 5.1), but sustained operation above ±8 mA may affect VOL/VOH margins and thermal performance. Total device current must remain within ±75 mA (Section 5.1) to avoid exceeding junction temperature limits in the TSSOP-16 package.
Is SN74AHCT367PWG4 pin-compatible with other AHCT-series buffers?
No, SN74AHCT367PWG4 is not pin-compatible with other AHCT-series hex or octal buffers. Its 16-pin TSSOP layout (PW) is unique to the 367 family's dual-group 4+2 architecture, differing from SN74AHCT244 (20-pin TSSOP) and SN74AHCT125 (14-pin SOIC). Pin functions are defined in Table 4-1 and Figure 4-1 of SCLS418I; substitution requires PCB layout revision even within the same AHCT family.
How should unused inputs be handled on SN74AHCT367PWG4?
All unused inputs on SN74AHCT367PWG4 must be tied to a valid logic level - either VCC or GND - to prevent floating states that cause excessive ICC, noise coupling, or undefined output behavior. Section 8.4.1 Layout Guidelines and Section 5.3 note explicitly require this. For example, unused 1A3 or 2A2 pins should connect directly to VCC or GND via short PCB traces; pull-up/down resistors are unnecessary unless signal integrity analysis indicates otherwise.
