Product details
Overview
74LVC16244ADGG-Q1J from Nexperia is an AEC-Q100 Grade 1 qualified 16-bit 3-state buffer/line driver in TSSOP48 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs/outputs, IOFF partial power-down support, and Schmitt-trigger inputs for noise immunity. It serves as a level-translating bus interface in automotive infotainment and body control modules.
For engineers reviewing the 74LVC16244ADGG-Q1J datasheet, 74LVC16244ADGG-Q1J pinout, 74LVC16244ADGG-Q1J application, or 74LVC16244ADGG-Q1J equivalent, key selection criteria include 5 V tolerance in mixed-voltage systems, -40 °C to +125 °C automotive temperature range, IOFF-enabled safe power sequencing, bus hold (on LVCH variant), and propagation delay ≤5.5 ns at 3.3 V.
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 section drives four outputs (e.g., 1Y0–1Y3) from corresponding inputs (1A0–1A3), enabling flexible partitioning as one 16-bit, two 8-bit, or four 4-bit drivers.
Schmitt-trigger inputs ensure robust operation with slow-rising signals; IOFF circuitry disables outputs and blocks backflow current when VCC = 0 V; and 5 V tolerance on all I/O pins allows direct interfacing with legacy 5 V logic without external 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 mixed-voltage SoC interfaces. |
| I/O Voltage Tolerance | 0 V to 5.5 V - Allows direct connection to 5 V peripherals without level-shifting components. |
| Propagation Delay (tpd) | ≤5.5 ns at VCC = 3.3 V - Supports high-speed data routing in automotive serial buses and display interfaces. |
| IOFF Leakage Current | ±10 μA at VCC = 0 V - Prevents damaging back-current during hot-swap or partial power-down sequences. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Ensures reliability during board assembly and field handling. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 pF loads over 10 cm PCB traces in ECU designs. |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch, 1.2 mm max height - optimized for high-density automotive PCB layouts with thermal and signal integrity in mind.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24) | Active-low output enable | Independently gates four 4-bit output groups into high-impedance state for bus sharing. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47,46,44,43 / 41,40,38,37 / 36,35,33,32 / 30,29,27,26) | Data inputs | Accept 3.3 V or 5 V logic; Schmitt-triggered for noise margin in noisy automotive environments. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2,3,5,6 / 8,9,11,12 / 13,14,16,17 / 19,20,22,23) | Buffered outputs | Non-inverting, 3-state, 5 V tolerant - drive downstream logic or parallel buses with minimal skew. |
| VCC (Pins 7, 18, 31, 42) | Supply voltage | Four distributed power pins reduce IR drop and improve PSRR in high-speed switching. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins minimize ground bounce and support clean signal return paths. |
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. |
| IOFF partial power-down | Outputs automatically enter high-Z and block reverse current when VCC is unpowered - critical for hot-plug subsystems. |
| 5 V tolerant I/O | Eliminates need for external level translators when interfacing with 5 V sensors, displays, or legacy MCUs. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V at VCC = 3.3 V - rejects EMI-induced glitches on long harness-connected lines. |
| Low dynamic power dissipation | CPD = 11.4 pF at VCC = 3.3 V - enables low-power operation in always-on vehicle networks. |
Applications
| Automotive Infotainment Display Interface | Body Control Module Bus Expansion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH16244ADGG-Q100 | Includes bus hold on all data inputs; identical pinout, package, and electrical specs otherwise. | Eliminates need for external pull-ups on unused inputs - reduces BOM count in modular ECUs with configurable I/O. | Select when input floating states must be actively held without external resistors. |
| SN74LVC16244ADGGR | Industrial-grade (non-automotive); same functional spec but not AEC-Q100 qualified; lower cost. | Not suitable for safety-critical or under-hood automotive use; acceptable for non-automotive industrial panels. | Select only for non-automotive applications where AEC-Q100 is not required. |
Compared with 74LVCH16244ADGG-Q100, the base 74LVC16244ADGG-Q1J lacks bus hold but offers identical automotive qualification and timing; versus SN74LVC16244ADGGR, it trades industrial cost savings for mandatory AEC-Q100 validation and extended temperature support.

FAQ
Is 74LVC16244ADGG-Q1J pin-compatible with 74LVCH16244ADGG-Q100?
Yes - both share identical TSSOP48 (SOT362-1) pinout, package dimensions, and electrical specifications. The only functional difference is that the LVCH variant includes bus hold circuitry on data inputs, while the LVC version does not. No PCB redesign is needed for substitution if bus hold is not required.
What is the maximum output current per pin at 3.3 V supply?
At VCC = 3.3 V, the device delivers ±24 mA per output pin under DC conditions, as specified in Table 6 (VOH/VOL) for IO = ±24 mA. This drive strength supports standard 50 Ω transmission lines and typical 50 pF capacitive loads found in automotive PCB interconnects.
Does this part support hot insertion or live insertion into a powered system?
Yes - the IOFF feature ensures outputs go high-impedance and block reverse current when VCC = 0 V, enabling safe hot insertion. However, inputs remain 5 V tolerant during insertion, and all I/O pins must be within absolute maximum ratings (−0.5 V to +6.5 V) before VCC ramp-up.
Can 74LVC16244ADGG-Q1J operate reliably at 1.2 V supply?
Yes - the device is fully specified down to 1.2 V supply (per Table 5), with propagation delay ≤11.0 ns and guaranteed VIH/VIL thresholds. At 1.2 V, static current is <20 μA, making it suitable for ultra-low-power wake-up circuits in automotive always-on domains.
