Product details
Overview
SN74LS367ANE4 from Texas Instruments is a hex buffer/line driver with three-state outputs, designed for bus-oriented bidirectional data transmission in TTL-level digital systems. It features six non-inverting channels, 16-pin PDIP packaging, operating at 0°C to 70°C, and supports high-impedance output control via two independent enable inputs (1G, 2G). It is commonly used in microprocessor address/data bus buffering and memory interface applications.
For engineers reviewing the SN74LS367ANE4 datasheet, SN74LS367ANE4 pinout, SN74LS367ANE4 application, or SN74LS367ANE4 equivalent, this page delivers verified functional identity, confirmed 16-pin PDIP mechanical and electrical specifications, validated three-state logic behavior, and direct alternative part comparisons grounded in TI's official family documentation and military-grade variants.
Technical Context
The SN74LS367ANE4 implements dual 3-bit non-inverting buffers with separate active-low enable controls (1G, 2G), allowing independent gating of two 3-bit groups. Each output drives up to 20 LS-TTL loads with guaranteed VOH ≥ 2.7 V and VOL ≤ 0.5 V under standard conditions.
It belongs to the 74LS logic family and uses bipolar transistor–transistor logic (TTL) with Schottky clamping for improved speed and reduced saturation delay. Its three-state outputs eliminate bus contention in shared-data-path architectures without requiring external pull-ups or direction-control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74LS (Low-power Schottky TTL) - ensures compatibility with legacy TTL systems and predictable noise margins. |
| Function | Hex non-inverting buffer with 3-state outputs - enables bidirectional bus driving without external direction logic. |
| Supply Voltage | VCC = 4.75 V to 5.25 V - matches standard TTL rail tolerance and avoids undervoltage lockout in industrial power supplies. |
| Output Drive | IOH = –0.4 mA / IOL = 8 mA - sufficient to drive 20 LS-TTL inputs directly, eliminating need for fanout buffers. |
| Propagation Delay | tpd = 15 ns max (at VCC = 5 V, TA = 25°C) - supports reliable operation in sub-33 MHz synchronous bus environments. |
| Operating Temperature | 0°C to 70°C - certified for commercial-grade embedded control and instrumentation applications. |
| Package | 16-pin PDIP (N) - through-hole compatible with prototyping, repair, and legacy PCB assembly workflows. |
Pinout & Package
SN74LS367ANE4 is housed in a 16-pin plastic dual in-line package (PDIP-N), 0.300-inch wide body, with 0.100-inch lead pitch and standard DIP footprint (JEDEC MS-001). Pin 1 is marked by a notch or dot; leads are tin-plated (NIPDAU) and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G | Active-low group enable (Group 1) | When low, enables Y1–Y3 outputs; high forces them into high-impedance state - allows selective activation of first 3-bit channel. |
| 1A1–1A3 | Inputs for Group 1 | Non-inverting inputs driving Y1–Y3; tolerate standard TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). |
| Y1–Y3 | Outputs for Group 1 | Three-state non-inverting outputs; high-impedance when 1G = high - prevents bus conflicts during idle cycles. |
| 2G | Active-low group enable (Group 2) | Independent control for Y4–Y6; enables full 6-bit isolation between two subsystems on same bus. |
| 1A4–1A6 | Inputs for Group 2 | Non-inverting inputs driving Y4–Y6; electrically identical to 1A1–1A3 - simplifies layout with uniform trace routing. |
| Y4–Y6 | Outputs for Group 2 | Three-state outputs mirroring Y1–Y3 behavior - supports split-bus arbitration or dual-processor memory sharing. |
| GND | Ground reference | Pin 8 - primary return path for all internal logic and output current; must be low-inductance connection in noise-sensitive designs. |
| VCC | Positive supply | Pin 16 - requires local 0.1 µF ceramic decoupling adjacent to pin to suppress switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-bit enables | Separate 1G and 2G pins allow simultaneous or staggered activation of two 3-bit data lanes - essential for multiplexed address/data buses. |
| Three-state outputs with TTL-compatible levels | VOH ≥ 2.7 V and VOL ≤ 0.5 V ensure robust interfacing with 74LS, 74ALS, and 74F families without level-shifting circuitry. |
| High noise immunity | Input hysteresis and guaranteed VIH/VIL margins (2.0 V/0.8 V) prevent metastability in electrically noisy industrial control cabinets. |
| Standard DIP footprint | 16-pin PDIP (N) package supports hand-soldering, socket-based testing, and backward compatibility with decades-old test fixtures and schematics. |
| RoHS-compliant NIPDAU finish | Tin immersion plating meets modern environmental compliance while maintaining solderability across reflow and wave processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer with three-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LS367AN | Identical functionality and pinout; differs only in marking (no "E4" suffix) and minor packaging labeling - same die, same electrical specs. | No functional difference; both rated for 0°C to 70°C, PDIP-16, RoHS-compliant NIPDAU finish. | Select SN74LS367AN if sourcing from distributors listing legacy stock without E4 suffix; fully interchangeable in BOMs and layouts. |
| SN74LS367ADR | SOIC-16 surface-mount variant with same logic function, but different package (D), moisture sensitivity level (MSL-1), and tape-and-reel packaging (2500 pcs/reel). | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or repair; better suited for high-volume automated production. | Choose SN74LS367ADR for new SMT-based designs targeting cost-effective volume manufacturing; not drop-in compatible with SN74LS367ANE4 footprints. |
Compared with SN74LS367AN and SN74LS367ADR, the SN74LS367ANE4 offers identical logic performance and through-hole assembly compatibility, making it optimal for lab validation, field repair, and low-to-medium volume commercial systems where manual soldering or socket use is required.

FAQ
What is the function of SN74LS367ANE4?
The SN74LS367ANE4 is a hex non-inverting buffer with three-state outputs, containing two independent 3-bit groups (Y1–Y3 and Y4–Y6), each controlled by its own active-low enable input (1G and 2G). It is used to isolate, drive, and gate digital signals on shared buses. All logic behavior, timing, and electrical characteristics of the SN74LS367ANE4 match the standard 74LS367 specification.
Is SN74LS367ANE4 RoHS compliant?
Yes, SN74LS367ANE4 is RoHS compliant, featuring a NiPdAu (NIPDAU) lead finish. This plating meets EU Directive 2011/65/EU requirements and supports both lead-free reflow and traditional wave soldering processes without compromising solder joint integrity or shelf life.
What is the maximum operating temperature range for SN74LS367ANE4?
The SN74LS367ANE4 is rated for operation from 0°C to 70°C, consistent with commercial-grade 74LS logic devices. This range supports deployment in office equipment, consumer electronics, and industrial control panels where ambient temperatures remain within standard indoor environments.
Can SN74LS367ANE4 replace SN74LS367AN in a design?
Yes, SN74LS367ANE4 can directly replace SN74LS367AN. Both share identical electrical specifications, pinout, package (PDIP-16), thermal ratings, and logic functionality. The "E4" suffix denotes TI's internal packaging and marking variant but does not affect performance, timing, or compatibility in any SN74LS367ANE4 application.
Does SN74LS367ANE4 support mixed-voltage interfacing?
SN74LS367ANE4 operates strictly at 5 V (4.75–5.25 V) and interfaces natively with TTL and compatible logic families (e.g., 74LS, 74ALS). It does not support mixed-voltage translation on its own; external level-shifting circuitry is required when connecting to 3.3 V or lower logic domains.
