Product details
Overview
IDT74LVCH16244APVG8 from Renesas Electronics is a 3.3V CMOS 16-bit non-inverting buffer/driver with 3-state outputs, 5V-tolerant I/O, bus-hold inputs, and ±24mA drive strength. It supports mixed 3.3V/5V systems, operates from –40°C to +85°C, and delivers <1ns output skew (tSK(o)) for synchronized data routing in high-density memory and bus interfaces.
For engineers reviewing the IDT74LVCH16244APVG8 datasheet, IDT74LVCH16244APVG8 pinout, IDT74LVCH16244APVG8 application, or IDT74LVCH16244APVG8 equivalent, key selection criteria include 5V-tolerant I/O compatibility, industrial-temperature operation, bus-hold input retention, ±24mA output drive, and TSSOP-48 package integration in voltage-translating bus driver designs.
Technical Context
The IDT74LVCH16244APVG8 implements four independent 4-bit buffers, each with active-low 3-state output-enable (OE) control and true (non-inverting) logic. Its bus-hold circuitry actively sustains input states at ±75μA, eliminating external pull resistors in floating-input scenarios.
It operates across VCC = 2.7V–3.6V, maintains 3.3V CMOS logic thresholds (VIH = 2.0V min, VIL = 0.8V max at VCC ≥ 2.7V), and achieves typical propagation delays of 1.1–4.1ns with <1ns output skew between any two outputs under matched switching conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports wide supply tolerance in noisy industrial rails and enables operation with degraded or marginally regulated 3.3V sources. |
| Output Drive | ±24mA - drives moderate-to-heavy capacitive loads (e.g., >30pF buses) without signal degradation or excessive rise/fall time penalties. |
| I/O Voltage Tolerance | 5V tolerant - allows direct interfacing with legacy 5V logic without level-shifting components in mixed-voltage backplanes or peripheral expansion. |
| Bus-Hold Current | ±75μA at VCC = 3V - retains last valid logic state on un-driven inputs, preventing metastability and eliminating need for discrete pull-up/down resistors. |
| Output Skew (tSK(o)) | <1ns - ensures deterministic timing alignment across all 16 outputs, critical for synchronous bus capture and parallel data integrity. |
| Propagation Delay | 1.1–4.1ns (typ/max at VCC = 3.3V) - enables reliable operation in high-speed address/data paths up to ~100MHz system clock domains. |
| Operating Temp | –40°C to +85°C - qualified for industrial environments including factory automation, telecom line cards, and embedded control systems. |
Pinout & Package
TSSOP-48 (Thin Shrink Small Outline Package, Green, 12.5mm × 6.1mm, 0.5mm pitch) with exposed pad not present; JEDEC-compliant footprint for automated assembly and thermal performance up to 100mW dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data Inputs (16 total) | True (non-inverting) inputs per 4-bit bank; all support 5V-tolerant operation and bus-hold functionality. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-State Outputs (16 total) | Active-high true outputs; placed in high-impedance state when corresponding OE is HIGH. |
| 1OE, 2OE, 3OE, 4OE | Active-Low Output Enable (4 total) | Independent control per 4-bit bank; LOW enables outputs, HIGH disables (Z-state); no internal pull-ups. |
| VCC (Pins 7, 24, 39, 48) | Power Supply | Four dedicated VCC pins reduce IR drop and improve noise immunity across the 48-pin array. |
| GND (Pins 4, 10, 21, 28, 34, 41) | Ground | Six GND pins provide low-inductance return paths and support simultaneous switching noise (SSN) mitigation. |
Key Features
| Feature | Design Value |
|---|---|
| 5V-Tolerant I/O | Enables seamless integration into legacy 5V subsystems without external level translators or voltage clamping networks. |
| Bus-Hold Inputs | Eliminates need for 10kΩ pull-up/down resistors on unused or intermittently driven inputs, reducing BOM count and PCB area. |
| ±24mA Output Drive | Supports driving 50Ω transmission lines or multi-load buses directly, reducing gate count and interconnect complexity in dense board layouts. |
| Low Output Skew (<1ns) | Guarantees aligned edge timing across all 16 outputs-essential for setup/hold compliance in parallel memory or FIFO interfaces. |

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 |
|---|---|---|---|
| SN74LVC16244ADGGR | Same 16-bit architecture, identical 5V-tolerant I/O and bus-hold, but rated only to +70°C (commercial temp) and lacks industrial qualification. | Not suitable for deployments requiring guaranteed operation above +70°C or below –40°C. | Select IDT74LVCH16244APVG8 when full industrial temperature range and Renesas' enhanced ESD robustness (>2000V HBM) are required. |
| 74ALVC16244PW,118 | Offers same pinout and function but uses NXP's ALVC process; lower ICCZ (3μA vs 10μA typ) and slightly higher VOL at 24mA (0.6V vs 0.55V). | Marginally better static power in battery-backed systems; minor VOL difference may affect noise margin in high-speed 3.3V-only buses. | Choose IDT74LVCH16244APVG8 where tighter output skew (<1ns vs 1.5ns) and proven bus-hold stability under transient load are prioritized. |
Compared with SN74LVC16244ADGGR and 74ALVC16244PW,118, the IDT74LVCH16244APVG8 uniquely combines industrial temperature qualification, sub-1ns output skew, and ±24mA drive in a single TSSOP-48 package-making it optimal for mission-critical bus buffering where timing determinism and environmental resilience are non-negotiable.

FAQ
What is the maximum output current rating for IDT74LVCH16244APVG8?
IDT74LVCH16244APVG8 is rated for ±24mA DC output current per pin under steady-state conditions, verified across the full industrial temperature range (–40°C to +85°C) and VCC = 2.7V–3.6V. This drive strength supports direct connection to 50Ω transmission lines and multi-load buses without external buffering, and is specified in the Output Drive Characteristics table of the official Renesas datasheet (DSC-4728/3, October 2015).
Does IDT74LVCH16244APVG8 support 5V logic inputs while powered at 3.3V?
Yes, IDT74LVCH16244APVG8 features fully 5V-tolerant I/O: all inputs, outputs, and I/O pins operate safely with voltages up to 5.5V regardless of VCC (2.7V–3.6V). This capability is explicitly confirmed in the datasheet's "Features" and "Absolute Maximum Ratings" sections, enabling direct interfacing with legacy 5V peripherals in mixed-voltage systems without level-shifting circuitry.
How does the bus-hold function work on IDT74LVCH16244APVG8?
IDT74LVCH16244APVG8 implements bus-hold on all input pins (1A1–4A4), retaining the last valid logic state when inputs float. It draws ±75μA sustain current (at VCC = 3V) to actively bias the input node, preventing undefined states and eliminating external pull-up/down resistors. This behavior is documented in the "BUS-HOLD CHARACTERISTICS" table and functional description of the Renesas datasheet DSC-4728/3.
What is the output skew specification for IDT74LVCH16244APVG8?
IDT74LVCH16244APVG8 guarantees output skew (tSK(o)) of less than 1ns between any two outputs switching in the same direction, measured under VCC = 3.3V ± 0.3V and TA = 25°C. This parameter is defined in the "SWITCHING CHARACTERISTICS" table and validated per JEDEC test methods, ensuring deterministic timing alignment critical for parallel bus applications like memory addressing and FIFO interfacing.
Which package type is used for IDT74LVCH16244APVG8?
IDT74LVCH16244APVG8 is supplied in a TSSOP-48 (Thin Shrink Small Outline Package) with green (RoHS-compliant) finish, 12.5mm × 6.1mm body size, and 0.5mm lead pitch. The "PVG" suffix in the part number explicitly denotes this package variant, and the pin configuration diagram and ordering information confirm its TSSOP-48 footprint per JEDEC MO-153 standards.
