Product details
Overview
74LVT244BPW-Q100 from Nexperia is an automotive-grade 3.3 V octal 3-state buffer/line driver in TSSOP20 package, featuring dual independent output enables (1OE, 2OE), bus-hold inputs eliminating external pull-ups, and ±64 mA/–32 mA drive capability. It operates from –40 °C to +85 °C and supports 5 V-tolerant inputs for mixed-voltage system interfacing in automotive body control modules.
For engineers reviewing the 74LVT244BPW-Q100 datasheet, 74LVT244BPW-Q100 pinout, 74LVT244BPW-Q100 application, or 74LVT244BPW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 3 qualification, 3.3 V BiCMOS logic compatibility, dual 4-bit 3-state control, overvoltage-tolerant inputs up to 5.5 V, and bus-hold functionality for floating input stabilization.
Technical Context
This device implements two independent 4-bit non-inverting buffers with active-low 3-state enable control per group (1OE controls Y0–Y3; 2OE controls Y0–Y3 of second group). Its BiCMOS architecture delivers TTL-compatible output drive while maintaining CMOS-level power efficiency and fast propagation delays (1.1 ns typical tPLH at 3.3 V).
The IOFF circuitry ensures partial power-down operation during supply loss, and bus-hold inputs maintain defined logic states without external resistors-critical for hot-swap and unconnected signal lines in automotive gateways and junction boxes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Enables stable operation across automotive battery transients and LDO tolerances. |
| Input Voltage Range | 0 V to 5.5 V - Allows direct interface with 5 V legacy systems without level shifters. |
| Output Drive | +64 mA sink / –32 mA source - Sufficient to drive multiple TTL loads or terminated transmission lines. |
| Propagation Delay | 1.1 ns (tPLH, typ @ 3.3 V) - Supports high-speed data routing in CAN/LIN gateway backplanes. |
| Bus-Hold Current | ±75 μA to ±140 μA - Actively maintains input state during float conditions without external components. |
| IOFF Leakage | ±100 μA @ VCC = 0 V - Prevents back-powering or signal corruption during power sequencing. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP20 (SOT360-1) package: 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, 1.1 mm max height - optimized for space-constrained automotive PCBs with automated assembly compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low enable inputs controlling first and second 4-bit output groups independently. |
| 2, 4, 6, 8 | 1A0–1A3 | Data inputs for first buffer group; bus-hold enabled by default. |
| 11, 13, 15, 17 | 2A0–2A3 | Data inputs for second buffer group; each supports 5.5 V tolerant operation. |
| 12, 14, 16, 18 | 1Y0–1Y3 | 3-state outputs for first group; high-impedance when 1OE = HIGH. |
| 3, 5, 7, 9 | 2Y0–2Y3 | 3-state outputs for second group; compatible with 5 V bus loading without current limiting. |
| 10 | GND | Ground reference for all I/O and internal circuitry; decoupling required near pin. |
| 20 | VCC | 3.3 V supply input; requires local 100 nF ceramic decoupling capacitor. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC244APWR | Non-automotive grade; rated –40 °C to +125 °C but not AEC-Q100 qualified; lower drive (±24 mA). | Lacks automotive qualification and bus-hold; suitable only for industrial or consumer designs. | Select only if AEC-Q100 compliance is unnecessary and cost is prioritized over robustness. |
| 74LVTH244PW,118 | Same family but non-Q100 version; identical pinout and electrical specs except no AEC validation. | Not qualified for automotive use; may require additional system-level qualification testing. | Use only for prototyping or non-safety-critical automotive subsystems where full Q100 traceability is waived. |
Compared with SN74LVC244APWR and 74LVTH244PW,118, the 74LVT244BPW-Q100 uniquely combines AEC-Q100 Grade 3 certification, bus-hold inputs, and ±64 mA/–32 mA drive-making it the sole drop-in solution for production automotive BCMs requiring zero external biasing and guaranteed qualification evidence.

FAQ
Is the 74LVT244BPW-Q100 pin-compatible with the standard 74LVT244B?
Yes, the 74LVT244BPW-Q100 shares identical pinout, electrical characteristics, and functional behavior with the non-automotive 74LVT244B, differing only in AEC-Q100 qualification, extended test coverage, and traceable lot documentation. No PCB or firmware changes are needed for migration.
Can this device drive a 5 V bus directly without level shifters?
Yes-the inputs tolerate up to 5.5 V regardless of VCC, and outputs can safely interface with 5 V buses due to overvoltage-tolerant design and no current injection limitation. The device draws no bus current when its outputs are tied to a 5 V rail, preventing unintended loading.
What is the purpose of the bus-hold feature, and how does it affect system design?
The bus-hold circuit actively maintains the last valid logic state on unused or unterminated inputs using ±75 μA to ±140 μA feedback current. This eliminates external pull-up/pull-down resistors, reduces BOM count, avoids floating-input metastability, and improves noise immunity in automotive harnesses with long stubs or intermittent connections.
Does the 74LVT244BPW-Q100 support live insertion in automotive modules?
Yes-its IOFF circuitry disables current flow between I/O pins when VCC = 0 V, and its ESD protection (HBM >2000 V, CDM >1000 V) meets automotive handling requirements. Combined with power-up 3-state behavior, this enables safe hot-plug operation in modular gateway or telematics units.
