Product details
Overview
74ALVCH162244PAG8 from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit non-inverting buffer/driver with 3-state outputs and integrated bus-hold circuitry, designed for memory address, clock, and bus interface applications. It delivers ±12mA drive strength, <500ps output skew, and operates across –40°C to +85°C industrial temperature range in a 48-pin TSSOP package.
For engineers reviewing the 74ALVCH162244PAG8 datasheet, 74ALVCH162244PAG8 pinout, 74ALVCH162244PAG8 application, or 74ALVCH162244PAG8 equivalent, key selection criteria include bus-hold functionality, rail-to-rail output swing, low static power (0.4μW typ.), and compatibility with 2.5V/2.7V/3.3V supply rails in high-density 3-state bus systems.
Technical Context
The 74ALVCH162244PAG8 implements four independent 4-bit buffers, each with active-low 3-state enable (OE), true output logic, and on-chip series termination resistors to suppress line noise under light loads. Its bus-hold inputs retain last valid state during high-impedance conditions, eliminating external pull-up/down resistors.
It uses 0.5μm dual-metal CMOS technology and supports three VCC operating ranges: 2.5V ±0.2V, 2.7V–3.6V, and 3.3V ±0.3V. Output drive is symmetrical (±12mA at threshold), with propagation delays as low as 4.2ns (tPLH/tPHL) and output disable time of 5.5ns (tPLZ) at 3.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V ±0.2V / 2.7V–3.6V / 3.3V ±0.3V - supports mixed-voltage system interfacing and legacy 2.5V compatibility |
| Drive Strength | ±12mA - enables direct driving of lightly loaded transmission lines without external termination |
| Output Skew (tSK(o)) | <500ps - ensures tight timing alignment across all 16 outputs for synchronous bus operation |
| Bus-Hold Current | ±75μA (VCC=3V) - maintains stable input logic state during bus float, removing need for 10kΩ pull resistors |
| Propagation Delay | 4.2ns (tPLH/tPHL, VCC=3.3V) - supports >200MHz data rates in address/data path buffering |
| Static ICC | 0.1μA typ. - reduces quiescent power in always-on control logic and standby modes |
| Input Capacitance | 5pF typ. - minimizes loading on upstream drivers and preserves signal integrity in fan-out-critical paths |
Pinout & Package
Package: 48-pin Thin Shrink Small Outline Package (TSSOP), lead-free and RoHS-compliant (Green). Body dimensions: 12.5mm × 6.1mm × 1.2mm, 0.5mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state output enable (4 per bank) | Independent control of four 4-bit output groups; enables partial bus isolation without full device disable |
| 1A1–4A4 | Data inputs (16 total) | All inputs feature bus-hold; pins 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 each have internal latching |
| 1Y1–4Y4 | True 3-state outputs (16 total) | Outputs drive high/low or enter high-Z; series resistors reduce ringing on unterminated traces |
| VCC (Pins 7, 24, 39, 48) | Power supply | Four dedicated VCC pins minimize IR drop and improve noise immunity across wide bus |
| GND (Pins 4, 10, 23, 31, 36, 45) | Ground return | Six GND pins provide low-inductance return paths for all output banks and reduce ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | VOH ≥ VCC–0.2V, VOL ≤ 0.2V - maximizes noise margin in 3.3V LVTTL and LVCMOS interfaces |
| Low switching noise | Integrated series output resistors - suppresses overshoot/ringing on PCB traces up to 15cm length |
| ESD protection | >2000V HBM, >200V MM - meets industrial IEC 61000-4-2 level 3 requirements without external TVS |
| Multi-voltage compatibility | Valid operation at 2.5V, 2.7V, and 3.3V - allows reuse across generations of ASIC/FPGA I/O standards |
| Ultra-low static power | 0.4μW typical ICC - enables use in always-on monitoring circuits without thermal impact |

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 |
|---|---|---|---|
| SN74ALVTH162244DGGR | TI part with TTL-compatible inputs (VIH = 2.0V min), higher ICC (1.5μA typ.), same 48-TSSOP package | Preferred where interfacing with legacy 5V-tolerant logic; lacks bus-hold, requiring external pull resistors | Select when VIH compatibility with older controllers is required and board space allows for pull-ups |
| 74LVC162244APAG | Nexperia part with identical pinout and bus-hold, but lower drive (±24mA), no 2.5V support, and 5.5ns max tPLZ | Better suited for cost-sensitive consumer designs; not qualified for extended industrial temp range (–40°C to +125°C only) | Choose for commercial-grade applications needing higher drive and lower BOM cost, with relaxed temp requirements |
Compared with SN74ALVTH162244DGGR and 74LVC162244APAG, the 74ALVCH162244PAG8 uniquely combines industrial temperature rating, bus-hold, multi-voltage operation, and sub-500ps skew-making it optimal for deterministic timing-critical embedded systems where reliability and signal integrity are non-negotiable.

FAQ
What is the operating temperature range for the 74ALVCH162244PAG8?
The 74ALVCH162244PAG8 is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the Absolute Maximum Ratings and DC/AC Electrical Characteristics tables in the official Renesas datasheet (DSC-4562/6, September 2016). The device maintains full parametric compliance-including bus-hold functionality, output drive, and timing-across this entire range without derating.
Does the 74ALVCH162244PAG8 require external pull-up or pull-down resistors on its inputs?
No, the 74ALVCH162244PAG8 does not require external pull-up or pull-down resistors because all input pins (1A1–4A4) feature integrated bus-hold circuitry. This function actively retains the last valid logic state when the input bus floats, with sustain currents of ±75μA at VCC = 3V. External resistors are unnecessary unless overriding bus-hold behavior for specific reset or initialization sequences.
What are the VCC supply voltage options supported by the 74ALVCH162244PAG8?
The 74ALVCH162244PAG8 supports three distinct VCC configurations: 2.5V ±0.2V, 2.7V to 3.6V, and 3.3V ±0.3V. These ranges allow interoperability with 2.5V ASICs, 3.3V FPGAs, and mixed-voltage backplanes. Operation outside these ranges violates Absolute Maximum Ratings and may cause latch-up or parametric failure. The 74ALVCH162244PAG8 must be powered within one of these specified windows to guarantee correct bus-hold, timing, and drive performance.
How many independent 3-state enable controls does the 74ALVCH162244PAG8 provide?
The 74ALVCH162244PAG8 provides four independent active-low 3-state output-enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a 4-bit output group (e.g., 1OE enables/disables outputs 1Y1–1Y4). This architecture enables granular bus partitioning-for example, isolating memory address bits 0–3 while keeping data bits 4–7 active-without disabling the entire 16-bit path.
Is the 74ALVCH162244PAG8 pin-compatible with other 48-pin TSSOP 16-bit buffers?
The 74ALVCH162244PAG8 has a unique pinout optimized for noise reduction and thermal distribution, including four VCC and six GND pins. While physically compatible with 48-pin TSSOP footprints, it is not pin-compatible with generic 16-bit buffers like 74LVC162244 or SN74ALVTH162244 due to differing OE placement, power pin allocation, and bus-hold pin assignment. Always verify pin mapping against the official Renesas pin configuration diagram before PCB layout.
