Product details
Overview
74LVC162244ADL,112 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. Used in high-speed parallel bus interfaces such as memory expansion and FPGA I/O bridging.
For engineers reviewing the 74LVC162244ADL,112 datasheet, 74LVC162244ADL,112 pinout, 74LVC162244ADL,112 application, or 74LVC162244ADL,112 equivalent, this device is selected for its dual-voltage interoperability, low-noise multibyte flow-through pinout, IOFF partial power-down capability, bus-hold-free operation (LVC variant), and guaranteed −40 °C to +125 °C performance.
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 30 Ω on-die series termination to suppress signal reflections on PCB traces up to 100 MHz.
All inputs feature Schmitt-trigger action (hysteresis ≥ 0.3 V at VCC = 3.3 V) and 5.5 V overvoltage tolerance; IOFF circuitry disables outputs during power-down to prevent backflow current. The LVC version lacks bus-hold but retains full 5 V tolerance and JEDEC-compliant voltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 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. |
| I/O Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V buses without external level shifters or clamping diodes. |
| Propagation Delay | 1.0 ns to 7.5 ns (VCC = 1.2 V to 3.6 V) - Supports >100 MHz data rates in parallel bus applications. |
| Output Termination | 30 Ω series resistor per output - Reduces overshoot/ringing on FR-4 traces without discrete resistors. |
| IOFF Current | ±10 μA max at VCC = 0 V - Prevents damaging back-current when powered off in hot-swap or partial-power-down systems. |
| Input Hysteresis | ≥0.3 V typical at VCC = 3.3 V - Rejects slow-rising/falling signals and improves noise margin in noisy environments. |
| Operating Temperature | −40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control and communications equipment. |
Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch. Pin 1 index marked; 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 four Y outputs independently; HIGH forces associated outputs into high-impedance state. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (pins 43–47, 37–41, 32–36, 26–30) | Data input | 16 total inputs; Schmitt-triggered, 5.5 V tolerant, no bus-hold (LVC variant). |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (pins 2–6, 8–12, 13–17, 19–23) | Non-inverting buffered output | Each includes 30 Ω series termination; 5.5 V tolerant; driven only when corresponding nOE is LOW. |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed supply pins minimize IR drop and improve PSRR across wide operating frequency range. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins reduce ground bounce and support low-noise switching of all 16 outputs simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates 16 discrete SMT resistors, saving PCB area and reducing BOM count in high-pin-count parallel interfaces. |
| 5.5 V tolerant I/O at 1.2 V–3.6 V VCC | Enables direct connection to legacy 5 V peripherals while powered from modern low-voltage rails-no external translators needed. |
| IOFF partial power-down protection | Prevents current backflow from live buses into unpowered sections, critical for hot-plug and modular system designs. |
| Schmitt-trigger inputs | Accepts slow or noisy signals (e.g., from mechanical switches or long cables) without false triggering or metastability. |
| Flow-through pinout architecture | Input/output pairs aligned across package width simplify PCB routing and minimize trace length mismatch in parallel buses. |
Applications
| Memory Expansion Interface | FPGA I/O Bridging |
|---|---|

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 |
|---|---|---|---|
| 74LVCH162244ADL,112 | Includes bus-hold on all data inputs; otherwise identical electrical specs and pinout. | Eliminates need for external pull-ups on unused inputs in floating-bus scenarios. | Select when unused inputs may float and board space prohibits external resistors. |
| SN74LVC162244ADGGR | Texas Instruments part in same TSSOP48 package; identical VCC range, 5 V tolerance, and 30 Ω termination. | Same functional behavior but different IOFF leakage spec (TI: ±2 μA vs Nexperia: ±10 μA at VCC = 0 V). | Select when tighter IOFF leakage is required in ultra-low-power standby modes. |
Compared with 74LVCH162244ADL,112, the LVC version saves cost where bus-hold is unnecessary; compared with SN74LVC162244ADGGR, it offers higher IOFF leakage tolerance-beneficial in systems where minor back-current is acceptable for simplified qualification.

FAQ
Is 74LVC162244ADL,112 pin-compatible with 74LVCH162244ADL,112?
Yes-both share identical TSSOP48 pinout, electrical specifications, and functional behavior. The only 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.
Can this device drive 50 Ω transmission lines directly?
No-it provides 30 Ω series termination, not 50 Ω. When driving a 50 Ω PCB trace, the total source impedance becomes 30 Ω + driver output impedance (~5 Ω), resulting in ~35 Ω source match. For precise 50 Ω matching, add a 15 Ω discrete series resistor.
What is the maximum clock rate supported for a 16-bit data bus?
Based on worst-case propagation delay of 7.5 ns (VCC = 1.2 V, TA = +125 °C), the maximum reliable toggle rate is 66 MHz (tcycle ≥ 2 × tpd). At 3.3 V and 25 °C, typical tpd is 2.7 ns, supporting >150 MHz burst-mode operation with proper layout.
Does this device support hot-swap insertion into a live 5 V backplane?
Yes-its 5.5 V-tolerant inputs and IOFF circuitry allow safe insertion while VCC is unpowered. With VCC = 0 V, input leakage remains ≤±10 μA and outputs enter high-Z state, preventing bus contention or backfeeding.
