Product details
Overview
74LVCH16244ADGV-QJ from Nexperia is a 16-bit CMOS buffer/line driver with 3-state outputs, four independent output enables (1OE–4OE), 5 V tolerant I/O, bus hold on all data inputs, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V supply and supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in automotive body control modules.
For engineers reviewing the 74LVCH16244ADGV-QJ datasheet, 74LVCH16244ADGV-QJ pinout, 74LVCH16244ADGV-QJ application, or 74LVCH16244ADGV-QJ equivalent, this device delivers deterministic 3-state timing, Schmitt-trigger input noise immunity, AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), and TVSOP48 package compatibility for high-density PCB layouts.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Each buffer group features Schmitt-trigger inputs for robust handling of slow-rising signals and bus hold circuitry eliminating external pull-ups on unused data inputs.
The IOFF circuit ensures outputs enter high-impedance state when VCC = 0 V, preventing backflow current during partial power-down. Input tolerance up to 5.5 V and output drive capability across 1.2 V–3.6 V supply allow seamless level translation without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - Enables operation in ultra-low-power 1.2 V systems and standard 3.3 V domains. |
| Input voltage range | 0 V to 5.5 V - Supports direct connection to 5 V TTL/CMOS sources without level shifters. |
| Propagation delay | 1.1 ns (typ) at VCC = 3.3 V - Ensures sub-nanosecond timing margin for high-speed bus buffering. |
| IOFF leakage | ±10 μA max at VCC = 0 V - Guarantees safe hot-insertion and partial power-down in modular ECUs. |
| Bus hold current | ±75 μA at VCC = 3.0 V - Maintains stable logic states on floating inputs without external resistors. |
| ESD rating | HBM > 2000 V, CDM > 1000 V - Meets automotive board-level ESD robustness requirements. |
| Ambient temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics. |
Pinout & Package
74LVCH16244ADGV-QJ uses the SOT480-1 (TVSOP48) package: 48-pin plastic thin shrink small outline, 4.4 mm body width, 0.4 mm lead pitch, and exposed thermal pad not connected internally.

| VCC (pins 7, 18, 31, 42) | Supply voltage | Four distributed power pins reduce switching noise and improve PSRR. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins minimize ground bounce and support high-speed signal integrity. |

FAQ
What is the maximum output drive strength at 3.3 V supply?
At VCC = 3.3 V, the device delivers ±24 mA output drive per pin (tested at VOH ≥ 2.2 V and VOL ≤ 0.55 V), sufficient to directly drive LEDs, relays, and standard CMOS/TTL loads without external amplification. This rating holds across the full -40 °C to +125 °C operating range per AEC-Q100 test conditions.
Can 74LVCH16244ADGV-QJ be used with a 1.2 V supply and 5 V inputs simultaneously?
Yes. The device is fully specified for 1.2 V VCC operation while accepting 0 V to 5.5 V input voltages. Internal clamping diodes and IOFF protection ensure safe operation even when VCC is powered down and 5 V signals remain present, satisfying automotive mixed-supply system requirements.
How does the bus hold circuit affect power consumption?
The bus hold draws ±75 μA per input at VCC = 3.0 V when holding a logic state, adding ~1.2 mA total worst-case for all 16 inputs. This is offset by eliminating 16 × 10 kΩ pull-up resistors (which would draw ~8 mA at 5 V), resulting in net power reduction in typical automotive idle states.
Is the TVSOP48 package compatible with standard reflow profiles?
Yes. The SOT480-1 (TVSOP48) package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its 0.4 mm pitch and 4.4 mm body width are compatible with standard automotive PCB assembly lines using Type 3 solder paste and nitrogen reflow.
