Product details
Overview
SN74HCS367QPWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive hex buffer with Schmitt-trigger inputs and 3-state outputs, configured as two independent banks (4-channel + 2-channel), operating from 2 V to 6 V supply, delivering ±7.8 mA output drive at 6 V, and featuring typical ICC of 100 nA for low-power body control modules.
For engineers reviewing the SN74HCS367QPWRQ1 datasheet, SN74HCS367QPWRQ1 pinout, SN74HCS367QPWRQ1 application, or SN74HCS367QPWRQ1 equivalent, key selection criteria include Schmitt-trigger noise immunity, dual-bank 3-state control, wettable-flank TSSOP-16 package compatibility, and automotive-grade thermal performance across –40°C to +125°C ambient.
Technical Context
The SN74HCS367QPWRQ1 implements six independent CMOS buffers partitioned into two logically isolated banks-Bank 1 (pins 1OE, 1A1–1A4, 1Y1–1Y4) and Bank 2 (pins 2OE, 2A1–2A2, 2Y1–2Y2)-each enabled independently via active-low OE signals. Each buffer performs non-inverting logic (Y = A) with hysteresis ΔVT ≥ 0.2 V at 2 V supply.
Schmitt-trigger inputs provide noise rejection up to ±0.5 V peak-to-peak at 2 V supply and support slow-edge signals without oscillation; 3-state outputs exhibit balanced sourcing/sinking capability (±7.8 mA at 6 V) and high-impedance leakage ≤ ±0.5 µA in disabled state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports direct interface with 3.3 V and 5 V automotive microcontrollers and sensors without level shifting. |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and body electronics applications. |
| Output Drive Strength | ±7.8 mA at 6 V - sufficient to drive multiple CMOS loads or moderate capacitive traces (≤50 pF) without signal degradation. |
| Input Hysteresis (ΔVT) | Min 0.2 V at 2 V, 0.6 V at 6 V - enables reliable switching in presence of EMI or mechanical switch bounce. |
| Quiescent Supply Current | Typ 100 nA at 6 V - enables always-on monitoring circuits with negligible battery drain in sleep mode. |
| Propagation Delay | 5 ns max at 6 V - ensures timing-critical signal routing (e.g., wake-up lines, sensor enable) meets sub-10 ns system budgets. |
| ESD Rating | HBM ±4 kV, CDM ±1.5 kV - exceeds automotive ESD robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP-16 (PW) package with wettable flanks, 5.00 mm × 4.40 mm body size, exposed thermal pad connected to GND or left floating per TI recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low bank enable controls high-impedance state for all outputs in respective bank; pull-up to VCC required for power-up safety. |
| 2, 4, 6, 10 | 1A1–1A4 | Bank 1 input channels - accept Schmitt-triggered signals from switches, sensors, or noisy MCU GPIOs. |
| 3, 5, 7, 9 | 1Y1–1Y4 | Bank 1 buffered outputs - drive downstream logic, LEDs, or bus lines with controlled rise/fall times. |
| 12, 14 | 2A1, 2A2 | Bank 2 input channels - isolated from Bank 1 for independent subsystem control (e.g., lighting + HVAC). |
| 11, 13 | 2Y1, 2Y2 | Bank 2 buffered outputs - enable/disable separate signal paths without cross-talk or contention. |
| 8 | GND | Ground reference - must be low-impedance connection; used for thermal pad tie in TSSOP variant. |
| 16 | VCC | Positive supply - requires local 0.1 µF bypass capacitor placed adjacent to pin per layout guidelines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer with Schmitt-trigger and 3-state applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCS367QPWR | Industrial-grade (non-AEC-Q100); identical electrical specs and pinout; lacks automotive qualification testing. | Not suitable for production automotive systems requiring AEC-Q100 documentation and traceability. | Select only for prototyping or non-safety-critical industrial control where temperature range ≤ 85°C suffices. |
| SN74LVTH16244ADGGR | 16-bit, non-Schmitt, TTL-compatible; higher drive (±24 mA), wider voltage (2.7–3.6 V), no hysteresis. | Requires external hysteresis circuitry for noisy environments; incompatible with slow-switching inputs like mechanical switches. | Choose only when driving high-capacitance buses (e.g., memory expansion) where Schmitt-trigger is unnecessary and higher speed is critical. |
Compared with SN74HCS367QPWRQ1, SN74HCS367QPWR omits automotive qualification but matches all electrical behavior, while SN74LVTH16244ADGGR trades Schmitt-trigger noise immunity for higher drive and speed in narrow-voltage applications-neither offers drop-in replacement capability without design validation.

FAQ
What is the maximum capacitive load SN74HCS367QPWRQ1 can drive while maintaining specified timing?
The SN74HCS367QPWRQ1 is characterized for CL = 50 pF in its switching characteristics table. Driving loads exceeding 50 pF increases propagation delay and transition time beyond datasheet limits (e.g., tpd rises from 5 ns to >12 ns at 6 V). For reliable operation, keep total output capacitance-including trace, connector, and receiver input-≤50 pF. Larger loads require series damping resistors or buffer staging.
How should unused inputs on SN74HCS367QPWRQ1 be terminated in an automotive design?
Unused inputs on SN74HCS367QPWRQ1 must be tied to VCC or GND using a 10 kΩ pull-up or pull-down resistor. Direct connection is acceptable only if the input is permanently unused. This prevents floating nodes that cause undefined logic states, increased ICC, and potential EMI susceptibility-critical for AEC-Q100 compliance and functional safety in automotive systems.
Does SN74HCS367QPWRQ1 support hot insertion or live board swapping?
SN74HCS367QPWRQ1 does not include explicit hot-swap protection features such as power-up 3-state or Ioff. Its absolute maximum ratings specify VI limits of –0.5 V to VCC + 0.5 V; applying input signals before VCC stabilization may exceed these limits. For hot-insertion scenarios, external series resistors and careful power sequencing are required-TI recommends tying both OE pins to VCC via pull-ups to ensure outputs remain high-Z until supply is valid.
What is the purpose of the thermal pad in the SN74HCS367QPWRQ1 TSSOP package?
The SN74HCS367QPWRQ1 TSSOP (PW) package does not include a thermal pad; that feature applies only to the WBQB (WQFN) variant. The PW package uses standard leadframe construction. Thermal management relies on PCB copper area connected to pins 8 (GND) and 16 (VCC), with recommended 0.1 µF bypass capacitor placement adjacent to VCC to minimize impedance and stabilize supply during switching transients.
Can SN74HCS367QPWRQ1 outputs be paralleled for higher current drive?
Yes-identical channels within SN74HCS367QPWRQ1 (e.g., 1Y1 and 1Y2) can be paralleled to increase sink/source capability, provided they share the same input (1A1 = 1A2) and OE state (1OE asserted). This configuration doubles effective drive strength (e.g., ±15.6 mA at 6 V) while maintaining matched timing. Avoid paralleling outputs across banks or with mismatched inputs to prevent shoot-through current.
