Product details
Overview
74FCT162244ETPVG from Renesas Electronics is a FAST CMOS 16-bit non-inverting buffer/line driver with balanced ±24mA output drive (industrial), 3.2ns max propagation delay (tPLH/tPHL), and flow-through pinout in 48-pin TSSOP package. It supports independent 4-bit/8-bit/16-bit 3-state control for bus interface applications in industrial control backplanes and high-speed data acquisition systems.
For engineers reviewing the 74FCT162244ETPVG datasheet, 74FCT162244ETPVG pinout, 74FCT162244ETPVG application, or 74FCT162244ETPVG equivalent, key selection criteria include output skew <0.5ns, ground bounce <0.6V at 5V, hysteresis-enhanced noise margin, and RoHS-compliant green TSSOP packaging.
Technical Context
The 74FCT162244ETPVG implements four independent 4-bit non-inverting buffers, each with dedicated active-low 3-state enable (xOE). Its 0.5µm CMOS process enables TTL-compatible input thresholds (VIH=2.0V min, VIL=0.8V max) while delivering 24mA sink/source drive at VCC=5.0V±10% across –40°C to +85°C.
Output drivers integrate current-limiting resistors and balanced impedance to suppress ground bounce (VOLP<0.6V) and undershoot, eliminating need for external series termination on loads <200pF. Propagation delay skew between any two outputs is guaranteed ≤0.5ns, supporting synchronous multi-bit signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with legacy 5V TTL/CMOS logic rails without level shifting |
| tPLH / tPHL | ≤3.2ns at CL=50pF - enables >300MHz data throughput in point-to-point bus interfaces |
| IOL / IOH | ±24mA (industrial) - drives 50Ω transmission lines or multiple TTL inputs directly |
| tSK(o) | <0.5ns - ensures deterministic timing alignment across all 16 outputs for parallel data paths |
| VOLP | <0.6V at VCC=5V - minimizes switching noise coupling into analog sections or adjacent digital channels |
| CIN / COUT | 6pF / 8pF max - reduces capacitive loading on driving sources and improves signal integrity at high frequencies |
| VIH / VIL | 2.0V min / 0.8V max - guarantees reliable recognition of standard TTL logic levels |
Pinout & Package
74FCT162244ETPVG is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), 12.5mm × 6.1mm body, 0.5mm pitch, RoHS-compliant green finish (PVG suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control per 4-bit group; enables partial bus isolation without full device disable |
| 1A1–4A4 | Non-inverting data inputs | 16 TTL-compatible inputs with hysteresis (100mV typical) for robust noise immunity |
| 1Y1–4Y4 | Non-inverting 3-state outputs | 16 balanced-output drivers with current limiting; supports hot-swap and live insertion |
| VCC (pins 10, 23, 36, 47) | Power supply | Four distributed VCC pins reduce IR drop and improve power delivery stability across wide die |
| GND (pins 11, 24, 37, 48, 1, 12) | Ground reference | Six GND pins provide low-inductance return paths, critical for minimizing ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA output drive | Enables direct drive of 50Ω PCB traces or up to 10 standard TTL loads without external buffers |
| Flow-through pinout | Input-to-output signal path runs linearly across package, simplifying layer routing and reducing crosstalk |
| Hysteresis on all inputs | 100mV typical threshold hysteresis eliminates chatter on slow-rising or noisy control signals |
| Guaranteed output skew <0.5ns | Ensures simultaneous valid data capture across 16-bit buses in high-speed ADC/DAC interfaces |
| Low ground bounce (<0.6V) | Maintains signal integrity in mixed-signal systems by preventing noise coupling into analog ground domains |
Applications
| Industrial Backplane Interface | High-Speed Data Acquisition |
|---|---|

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 |
|---|---|---|---|
| SN74FCT162244ATPVR | Slower max tPLH/tPHL (4.1ns vs. 3.2ns); same 48-TSSOP package and pinout | Lower-speed industrial bus interfaces where timing margin exceeds 4ns | Select when cost sensitivity outweighs need for sub-3.5ns propagation delay |
| 74LVCH162244APAG | 3.3V-only operation (1.65–3.6V); higher drive (±24mA @ 3.3V) but incompatible VCC range | Modern low-voltage systems requiring 3.3V logic compatibility and level translation | Choose only if migrating from 5V to 3.3V infrastructure; not a drop-in replacement |
Compared with SN74FCT162244ATPVR and 74LVCH162244APAG, the 74FCT162244ETPVG delivers the fastest propagation delay in the FCT family at 5V, making it optimal for timing-critical industrial backplanes where every 0.9ns of margin matters - while retaining full pin compatibility with earlier FCT variants.

FAQ
What is the operating temperature range for the 74FCT162244ETPVG?
The 74FCT162244ETPVG is rated for industrial temperature operation from –40°C to +85°C. This range is explicitly defined in the ordering information and electrical characteristics tables of the official Renesas datasheet, and the "E" suffix in the part number denotes the industrial-grade version with guaranteed performance across this full span.
Is the 74FCT162244ETPVG pin-compatible with older ABT-series buffers?
Yes, the 74FCT162244ETPVG is a plug-in replacement for 74ABT16244 devices. The datasheet explicitly states "These parts are plug in replacements for 54/74ABT16244", and the pin configuration diagram confirms identical 48-pin TSSOP mapping for all inputs, outputs, and power terminals.
Does the 74FCT162244ETPVG support hot-swap or live-insertion applications?
Yes, the 74FCT162244ETPVG supports live insertion due to its 3-state outputs with controlled turn-on/off times (tPZH ≤4.4ns, tPHZ ≤3.6ns), current-limited drivers, and hysteresis-enhanced inputs. These features prevent bus contention and transient overcurrent during partial power-up sequences.
What is the maximum capacitive load the 74FCT162244ETPVG can drive while maintaining specified timing?
The 74FCT162244ETPVG's switching characteristics are specified at CL = 50pF, and the datasheet notes that its output structure "reduces the need for external series terminating resistors while still providing very high speed operation for loads of less than 200pF". Thus, it reliably maintains timing specs up to 200pF.
How does the hysteresis on inputs improve system reliability for the 74FCT162244ETPVG?
The 74FCT162244ETPVG features typical 100mV of input hysteresis, which widens the voltage transition window between logic HIGH and LOW states. This prevents oscillation or metastability on slow-rising signals - such as those from mechanical switches, long cables, or noisy sensor interfaces - ensuring clean, glitch-free output transitions.
