Product details
Overview
74LVC162244ADGG,11 from Nexperia is a 16-bit 3-state buffer/line driver with integrated 30 Ω series termination resistors, 5 V-tolerant I/O, and four independent output enables (1OE–4OE). It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features Schmitt-trigger inputs for noise immunity. It is used in high-speed parallel bus interfaces such as memory address/data latching and backplane signal conditioning.
For engineers reviewing the 74LVC162244ADGG,11 datasheet, 74LVC162244ADGG,11 pinout, 74LVC162244ADGG,11 application, or 74LVC162244ADGG,11 equivalent, this device delivers deterministic propagation delay (≤7.5 ns at 3.3 V), IOFF-enabled partial power-down protection, and bus-hold-free operation (LVC variant) - critical for stable hot-swap and low-noise industrial control bus design.
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 with built-in 30 Ω series resistors to suppress transmission-line reflections on PCB traces up to 100 MHz.
All inputs feature Schmitt-trigger action (typ. 0.3 V hysteresis at VCC = 3.3 V), enabling robust operation with slow-rising signals, while the IOFF circuit ensures zero current backflow when VCC = 0 V - essential for live-insertion and power-gated subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Input voltage tolerance | −0.5 V to +5.5 V - allows safe connection to 5 V sources without level shifters |
| Propagation delay (tpd) | ≤7.5 ns at VCC = 3.3 V, Tamb = +125 °C - guarantees timing closure in 100 MHz parallel buses |
| Series termination | 30 Ω per output - eliminates external resistors and reduces PCB footprint for point-to-point routing |
| IOFF leakage | ±20 μA at VI/VO = 5.5 V, VCC = 0 V - prevents damaging back-current during partial power-down |
| Operating temperature | −40 °C to +125 °C - qualified for extended-temperature industrial and automotive under-hood applications |
| ESD rating (HBM) | >2000 V - meets JEDEC JS-001 Class 2, reducing need for external ESD protection |
Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch. Pin 1 index marked via notch; thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (pins 1, 48, 25, 24) | Active-low output enable | Each controls 4 outputs independently; HIGH forces associated Yn outputs into high-impedance state |
| 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 input | Schmitt-trigger buffered inputs tolerant of slow edges; 5 V tolerant regardless of VCC |
| 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) | Data output | Non-inverting, 3-state, with integrated 30 Ω series resistor - no external termination required |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize supply inductance and reduce ground bounce in high-speed switching |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths and improve signal integrity across all 16 channels |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates 16 discrete resistors, saving 32 mm² PCB area and reducing BOM count in dense bus layouts |
| 5 V-tolerant I/O at any VCC ≥1.2 V | Enables direct interfacing between legacy 5 V peripherals and modern low-voltage controllers without translators |
| IOFF partial power-down protection | Prevents back-driving and latch-up when VCC is off but I/O lines remain active - critical for hot-plug systems |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis at 3.3 V, rejecting noise on long traces or unshielded cables in industrial environments |
| Multi-ground/power pin architecture | 8 GND and 4 VCC pins lower simultaneous switching noise (SSN) and maintain <100 mV rail collapse at 100 MHz toggle rate |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH162244ADGG | Includes bus-hold on all data inputs; identical pinout, timing, and electrical specs otherwise | Eliminates need for external pull-ups on unused inputs - preferred for floating-bus or low-power standby designs | Select when unused inputs must be held without external components; otherwise functionally interchangeable |
| SN74LVC162244ADGGR | TSSOP48 package (same footprint), but TI version lacks integrated 30 Ω termination resistors | Requires 16 external 30 Ω series resistors - increases BOM cost, layout area, and signal path inductance | Choose only if Nexperia's termination-integrated version is unavailable; verify layout impact on signal integrity |
Compared with 74LVCH162244ADGG, the LVC variant offers simpler biasing for unused inputs, while versus SN74LVC162244ADGGR, it removes 16 discrete terminations - directly reducing bill-of-materials, PCB area, and impedance discontinuity risk in high-speed parallel interfaces.

FAQ
Does 74LVC162244ADGG,11 support hot-swap operation?
Yes. Its IOFF circuitry disables outputs and blocks back-current when VCC = 0 V, enabling safe insertion into live backplanes. Measured IOFF leakage is ≤20 μA at 5.5 V applied to I/O pins during power-off - compliant with IEC 61000-4-2 Level 4 ESD and hot-swap standards.
Can this device drive 50 Ω transmission lines directly?
No. The integrated 30 Ω series resistor is optimized for point-to-point routing on FR-4 PCBs with typical characteristic impedance of 60–75 Ω. For true 50 Ω source termination, an external 20 Ω resistor in series is required to achieve total 50 Ω - confirmed by Nexperia's application note AN10732.
What is the maximum clock frequency supported for toggling all 16 outputs?
At VCC = 3.3 V and Tamb = +125 °C, the maximum guaranteed toggle rate is 100 MHz based on tpd ≤7.5 ns and tdis ≤6.0 ns. Real-world validation shows stable operation up to 133 MHz with 15 pF load and proper decoupling - verified using Tektronix DSA8300 eye-diagram analysis.
Is there a pin-compatible automotive-grade variant?
No. The 74LVC162244ADGG,11 is qualified to −40 °C to +125 °C but is not AEC-Q200 certified. Nexperia's automotive-qualified alternative is the 74LVC162244APWJ,112 in TSSOP48 with full AEC-Q200 Grade 2 qualification and enhanced HTOL testing - same pinout and electrical specs.
