Product details
Overview
74ALVCH162244PAG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit buffer/driver with 3-state outputs and integrated bus-hold circuitry, designed for memory address, clock, and bus-oriented signal routing in industrial systems. It delivers ±12mA drive strength, <500ps output skew, rail-to-rail swing, and operates across –40°C to +85°C.
For engineers reviewing the 74ALVCH162244PAG datasheet, 74ALVCH162244PAG pinout, 74ALVCH162244PAG application, or 74ALVCH162244PAG equivalent, key selection criteria include 3-state timing (tPZH/tPHZ), bus-hold sustain current (±75μA at VCC=3V), industrial temperature compliance, TSSOP-48 package footprint, and compatibility with mixed-voltage 2.5V/3.3V I/O domains.
Technical Context
The 74ALVCH162244PAG implements four independent 4-bit non-inverting buffers, each with active-low 3-state enable (OE) and bus-hold on all inputs. Its dual-metal CMOS process enables low static power (0.4μW typ.) and balanced ±12mA output drive capability.
Output structure includes integrated series resistors to suppress switching noise under light loads. Bus-hold retains last valid input state during high-impedance conditions, eliminating external pull-up/down resistors and preventing floating inputs in unterminated buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V ±0.2V, 2.7V–3.6V extended - supports mixed-voltage system interfacing and brown-out tolerance |
| Drive Strength | ±12mA at VCC=3V - sufficient to drive standard 50Ω transmission lines or multiple CMOS inputs without external buffering |
| Output Skew | ≤500ps - ensures tight timing alignment across all 16 outputs for synchronous bus applications |
| Bus-Hold Current | ±75μA at VI=2V/0.8V (VCC=3V) - maintains stable logic state with minimal current draw during bus float |
| tPZH / tPHZ | 5.6ns / 5.5ns max (VCC=3.3V) - enables high-speed enable/disable control of data paths in real-time systems |
| Input Capacitance | 5–7pF - minimizes loading on upstream drivers and preserves signal integrity in high-frequency traces |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded control, automation, and communications equipment |
Pinout & Package
TSSOP-48 (Thin Shrink Small Outline Package, Green, 12.5mm × 6.1mm × 1.2mm body height, 0.5mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control per 4-bit bank; assertion disables corresponding Y outputs to high-impedance |
| 1A1–4A4 | Data inputs | All 16 inputs feature bus-hold; retain last logic state when un-driven, eliminating external biasing |
| 1Y1–4Y4 | True non-inverting outputs | Each output drives ±12mA; internal series resistance reduces ringing on unterminated lines |
| VCC (Pins 7, 24, 39, 48) | Power supply | Four dedicated VCC pins reduce IR drop and improve noise immunity across wide TSSOP body |
| GND (Pins 4, 10, 25, 32, 41) | Ground reference | Five GND pins provide low-inductance return paths and support clean signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | VOH ≥ VCC–0.2V, VOL ≤ 0.2V - maximizes noise margin in noisy industrial environments |
| Low static power | ICCL ≤ 40μA (VCC=3.6V) - enables always-on buffer operation in power-constrained edge nodes |
| ESD robustness | ≥2000V HBM, ≥200V MM - withstands handling and board-level ESD events without protection diodes |
| Output skew control | tSK(o) < 500ps - guarantees deterministic timing for parallel data capture in FPGA/ASIC interfaces |
| Extended voltage range | Operates down to 2.5V - interoperable with legacy 2.5V logic and future-proof for voltage scaling |
Applications
| Memory Address Buffering | Clock Distribution |
|---|---|
Use Scenario: Driving address lines from an MCU or FPGA to multiple SRAM/Flash devices in an industrial PLC backplane. IC Role / Device Role / Timing Role: Non-inverting 16-bit buffer with per-bank 3-state control isolates address bus segments during multi-device access cycles. Use Value: Bus-hold prevents address corruption during bus turnaround; ±12mA drive ensures fast edge rates across 10cm PCB traces. | Use Scenario: Distributing a system clock to four synchronous peripherals (ADC, DAC, UART, timer) with matched skew. IC Role / Device Role / Timing Role: Low-skew 3-state driver enabling dynamic clock gating per peripheral without signal degradation. Use Value: ≤500ps inter-output skew maintains setup/hold margins; rail-to-rail swing sustains jitter-free clock edges. |
| Industrial Bus Transceiver Interface | Legacy System Voltage Translation |
Use Scenario: Interfacing a 3.3V microcontroller to a 5V-tolerant industrial fieldbus controller via level-shifted control signals. IC Role / Device Role / Timing Role: 3-state buffer with bus-hold acting as a fail-safe interface layer during hot-plug or reset transitions. Use Value: Prevents floating control lines (e.g., chip select, write enable) that could trigger spurious bus activity. | Use Scenario: Connecting a modern 2.5V FPGA I/O bank to legacy 3.3V peripheral logic in retrofit equipment. IC Role / Device Role / Timing Role: Bidirectional voltage-domain bridge using 3-state enables to isolate direction and prevent contention. Use Value: Extended VCC range (2.5V–3.6V) allows native operation at either rail; bus-hold stabilizes inputs during voltage transition windows. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH162244VR | TI part with identical pinout, same bus-hold and drive specs, but supports 2.3V–3.6V VCC and includes TTL-compatible inputs | Preferred where legacy 5V-tolerant inputs required; slightly higher ICCZ (750μA vs. 40μA) | Select when interfacing to older 5V logic families without level shifters |
| 74LVC162244APAG | Nexperia part in same TSSOP-48 package; no bus-hold; lower drive (±24mA), wider VCC (1.65V–3.6V), higher tPZH (7.5ns) | Suitable for cost-sensitive consumer designs; requires external pull-ups if bus float is possible | Choose when bus-hold is unnecessary and higher drive or ultra-low VCC operation is prioritized |
Compared with SN74ALVTH162244VR and 74LVC162244APAG, the 74ALVCH162244PAG uniquely balances industrial temperature reliability, bus-hold safety, and sub-6ns enable timing - making it optimal for fault-tolerant embedded control where input stability and timing predictability are critical.

FAQ
What is the operating temperature range supported by the 74ALVCH162244PAG?
The 74ALVCH162244PAG is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the device's absolute maximum ratings and DC/AC electrical specifications, ensuring reliable performance in harsh environments such as factory automation controllers, outdoor base stations, and motor drive enclosures where ambient thermal cycling occurs.
Does the 74ALVCH162244PAG require external pull-up or pull-down resistors on its inputs?
No, the 74ALVCH162244PAG does not require external pull-up or pull-down resistors because all 16 input pins (1A1–4A4) feature integrated bus-hold circuitry. This function actively maintains the last valid logic state during high-impedance conditions, eliminating floating inputs - a key reliability feature confirmed in the Bus-Hold Characteristics table of the official datasheet for the 74ALVCH162244PAG.
What is the maximum output skew specification for the 74ALVCH162244PAG?
The maximum output skew (tSK(o)) for the 74ALVCH162244PAG is 500ps under standard operating conditions (VCC = 3.3V ± 0.3V, TA = –40°C to +85°C). This value represents the worst-case timing mismatch between any two outputs switching in the same direction within the same package, and is explicitly specified in the Switching Characteristics table for the 74ALVCH162244PAG.
Can the 74ALVCH162244PAG operate at 2.5V supply voltage?
Yes, the 74ALVCH162244PAG supports 2.5V ± 0.2V operation as a defined normal range, with full DC and AC specifications guaranteed. The datasheet confirms VIH/VIL thresholds, drive strength (±12mA), and timing parameters (e.g., tPLH = 4.2ns min) are all characterized at 2.5V - enabling seamless integration into mixed-voltage systems alongside 2.5V FPGAs or ASICs.
How many independent 3-state enable inputs does the 74ALVCH162244PAG have?
The 74ALVCH162244PAG has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE - one for each 4-bit buffer section. Each OE input controls the corresponding group of four outputs (e.g., 1OE enables/disables 1Y1–1Y4), allowing granular bus segmentation and power-aware signal gating, as documented in the Function Table and Pin Description sections for the 74ALVCH162244PAG.
