Product details
Overview
74FCT162244ETPVG8 from Renesas Electronics is a 16-bit non-inverting 3-state buffer/line driver in TSSOP-48 package, designed for high-speed bus interface and signal buffering in industrial systems. It delivers ±24mA balanced output drive at 5V, tPLH/tPHL ≤ 3.2ns (CL = 50pF), and <0.5ns output skew, supporting noise-immune data routing in backplane and memory subsystems.
For engineers reviewing the 74FCT162244ETPVG8 datasheet, 74FCT162244ETPVG8 pinout, 74FCT162244ETPVG8 application, or 74FCT162244ETPVG8 equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), flow-through pinout for PCB layout simplification, hysteresis-enhanced noise margin on all inputs, and compatibility with ABT16244-based designs requiring lower ground bounce and tighter timing control.
Technical Context
This device implements four independent 4-bit buffered channels, each with dedicated active-low 3-state enable (xOE) allowing flexible 4-bit, 8-bit, or full 16-bit bus control. Its CMOS architecture uses 0.5µm process with current-limiting output resistors to suppress ground bounce (VOLP < 0.6V) and undershoot while maintaining fast edge rates for <200pF loads.
All inputs feature built-in hysteresis (~100mV), improving immunity to slow-rising signals and system-level noise. The balanced ±24mA (industrial) output drive ensures matched rise/fall times and enables direct driving of transmission lines without external termination resistors in point-to-point configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-supply operation compatible with legacy TTL/CMOS logic families |
| tPLH / tPHL | ≤3.2ns at CL = 50pF - enables >300MHz data throughput in short-bus applications |
| IOL / IOH | ±24mA (industrial) - sufficient to drive multiple LVTTL inputs or 50Ω stubs without fanout degradation |
| tSK(o) | <0.5ns - guarantees deterministic timing alignment across all 16 outputs for synchronous bus capture |
| CIN / COUT | Max 6pF / 8pF - minimizes capacitive loading on upstream drivers and preserves signal integrity |
| VIL / VIH | 0.8V / 2.0V - TTL-compatible input thresholds ensure interoperability with 5V microcontrollers and FPGAs |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded control, instrumentation, and communications equipment |

Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the operating temperature range specified for the 74FCT162244ETPVG8?
The 74FCT162244ETPVG8 is rated for industrial temperature operation from –40°C to +85°C. This specification is guaranteed across all electrical parameters including propagation delay, output drive, and input thresholds. The device meets this range using Renesas' qualified industrial process and is tested per JEDEC JESD22-A108. No derating is required within this envelope, and the 74FCT162244ETPVG8 maintains full timing compliance throughout.
Does the 74FCT162244ETPVG8 support true 5V TTL compatibility?
Yes, the 74FCT162244ETPVG8 provides full 5V TTL compatibility with VIH = 2.0V (min) and VIL = 0.8V (max), matching standard TTL logic thresholds. Its inputs accept TTL voltage levels directly, and its outputs drive standard TTL loads with ±24mA sink/source capability. Unlike LVTTL or LVCMOS variants, the 74FCT162244ETPVG8 requires no level-shifting circuitry when interfacing with legacy 5V microcontrollers, CPLDs, or memory devices.
How does the hysteresis on inputs benefit system design with the 74FCT162244ETPVG8?
The 74FCT162244ETPVG8 incorporates ~100mV of input hysteresis on all 16 data and enable inputs. This improves noise margin by preventing chatter on slow-rising signals-such as power-on resets, mechanical switch debounces, or long-trace clock distribution-and eliminates need for external RC filters. In industrial environments with EMI or ground shifts, hysteresis ensures deterministic sampling even when input edges exceed 10ns rise/fall times, directly enhancing system reliability without added components.
Can the 74FCT162244ETPVG8 be used as a direct replacement for 74ABT16244 devices?
Yes, the 74FCT162244ETPVG8 is explicitly designed as a plug-in replacement for 74ABT16244 in 5V systems. It shares identical pinout, function table, and DC specifications while offering improvements: faster propagation delay (3.2ns vs. 4.9ns), lower ground bounce (<0.6V vs. >1.0V), built-in input hysteresis, and tighter output skew (<0.5ns). No PCB or firmware changes are needed-only validation of timing margins under worst-case load conditions is recommended.
What package type and RoHS status does the 74FCT162244ETPVG8 use?
The 74FCT162244ETPVG8 is supplied in a RoHS-compliant, green (lead-free) TSSOP-48 package (PVG suffix), measuring 12.5mm × 6.1mm with 0.5mm lead pitch. It conforms to JEDEC MO-153 and features nickel-palladium-gold (NiPdAu) lead finish. The "PVG" designation confirms halogen-free molding compound and exemption from EU Directive 2011/65/EU Annex III Category 7(b) for lead content in high-melting-temperature solder alloys.
