Product details
Overview
74LVC244APW-Q100 from Nexperia is an automotive-grade octal non-inverting 3-state buffer/line driver in TSSOP20 package, operating from 1.2 V to 3.6 V supply, with 5 V-tolerant inputs/outputs and Schmitt-trigger inputs for noise immunity. It supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in body control modules and infotainment gateways.
For engineers reviewing the 74LVC244APW-Q100 datasheet, 74LVC244APW-Q100 pinout, 74LVC244APW-Q100 application, or 74LVC244APW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), bus hold capability (in LVCH variant), propagation delay down to 2.9 ns at 3.3 V, and 20-pin TSSOP package with side-wettable flanks for AOI compatibility.
Technical Context
This device implements two independent 4-bit non-inverting buffer groups (1A0–1A3 and 2A0–2A3), each controlled by dedicated active-low output enable pins (1OE, 2OE). Outputs enter high-impedance state when respective OE is HIGH, enabling bidirectional bus sharing without external logic.
Schmitt-trigger inputs ensure robust operation with slow-rising signals (Δt/ΔV up to 20 ns/V at VCC = 1.2 V), while 5.5 V absolute max input voltage and 5 V tolerant 3-state outputs allow direct connection to legacy 5 V systems without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables operation across low-power microcontrollers and standard 3.3 V I/O rails. |
| Input Voltage Tolerance | Up to 5.5 V - Permits direct interface with 5 V logic without external clamping or translation. |
| Propagation Delay (tpd) | 2.9 ns typical at VCC = 3.3 V - Supports high-speed data routing in automotive serial buses and sensor interfaces. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 pF loads with <7.5 ns disable time, meeting CAN/LIN peripheral timing margins. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Ensures robustness during automated PCB assembly and field service handling. |
Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enable controls Group 1 and Group 2 independently; HIGH forces associated Y outputs into high-Z. |
| 2, 4, 6, 8 | 1A0–1A3 | Data inputs for first buffer group; Schmitt-triggered for noise margin on noisy automotive harnesses. |
| 3, 5, 7, 9 | 2Y0–2Y3 | Outputs for second buffer group; 5 V tolerant in 3-state mode, enabling shared bus arbitration. |
| 10 | GND | Reference ground plane; decoupling capacitor must be placed within 3 mm for stable switching noise suppression. |
| 11, 13, 15, 17 | 2A0–2A3 | Data inputs for second buffer group; electrically identical to 1A0–1A3 with same VIH/VIL thresholds. |
| 12, 14, 16, 18 | 1Y0–1Y3 | Outputs for first buffer group; driven low/high per input state when 1OE = LOW; high-Z otherwise. |
| 20 | VCC | Primary supply rail; requires local 100 nF ceramic decoupling adjacent to pin to maintain <100 mV ripple during 24 mA switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| 5 V tolerant I/O | Inputs accept 0–5.5 V; outputs tolerate 0–5.5 V in 3-state - eliminates need for discrete level translators in mixed-voltage ECUs. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V at VCC = 3.3 V - rejects EMI-induced glitches on long PCB traces or cable-connected sensors. |
| Bus hold (LVCH variant only) | IBHL = 75 μA at VCC = 3.0 V - maintains valid logic state on unused data inputs without external pull-ups, reducing BOM count. |
| Side-wettable flanks | Package SOT360-1 enables automated optical inspection of solder joints - critical for zero-defect automotive manufacturing. |
Applications
| Body Control Module (BCM) | Infotainment Gateway |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH244APW-Q100 | Includes bus hold circuit on all data inputs; identical pinout and electrical specs otherwise. | Eliminates need for external pull-up resistors on unused inputs in low-pin-count designs. | Select when minimizing external components on sparse PCB layouts; no change to OE control or timing behavior. |
| SN74LVC244AQDRQ1 | Texas Instruments part; same AEC-Q100 Grade 1 rating but SOIC-20 package (SOT163-1), no side-wettable flanks. | Lacks AOI-compatible solder joint inspection; slightly higher thermal resistance (12.3 mW/K derating above 109 °C). | Choose for legacy board rework where SOIC footprint is fixed; avoid for new designs requiring automated optical inspection. |
Compared with 74LVCH244APW-Q100, the bus hold feature reduces BOM cost but adds ~500 μA static current per held input; versus SN74LVC244AQDRQ1, the TSSOP20 package offers 30 % smaller footprint and superior thermal performance in dense automotive modules.

FAQ
Is 74LVC244APW-Q100 pin-compatible with 74LVCH244APW-Q100?
Yes - both share identical TSSOP20 pinout (SOT360-1), supply range, and timing specs. The only functional difference is that 74LVCH244APW-Q100 integrates bus hold on all data inputs, while 74LVC244APW-Q100 does not. No layout changes are required for substitution.
Can this buffer drive a 50 Ω transmission line directly?
No - it is not designed as a line driver for impedance-matched transmission lines. Its ±24 mA output drive targets capacitive loads up to 50 pF. For 50 Ω routing, use a dedicated high-speed line driver IC or add series termination.
What is the maximum clock frequency supported for data throughput?
The device has no internal clock; it is combinational. Maximum usable data rate depends on system-level timing: with 2.9 ns tpd and 1.5 ns tdis at 3.3 V, reliable operation is confirmed up to 100 Mbps NRZ for short traces (<5 cm) with proper termination and layout.
Does VCC = 0 V disable all outputs?
Yes - when VCC = 0 V, outputs enter high-impedance state regardless of OE pin state, and input leakage is limited to ±10 μA (IOFF). This "power-off protection" prevents back-powering of upstream circuits during hot-swap or brown-out conditions.
