Product details
Overview
74FCT162244CTPAG from Renesas Electronics is a FAST CMOS 16-bit non-inverting 3-state buffer/line driver with balanced ±24mA output drive (industrial), 4.1ns max propagation delay (tPLH/tPHL), and flow-through pinout in 48-pin TSSOP package. It serves as a high-speed, low-noise bus interface for industrial control backplanes and memory address/data buffering.
For engineers reviewing the 74FCT162244CTPAG datasheet, 74FCT162244CTPAG pinout, 74FCT162244CTPAG application, or 74FCT162244CTPAG equivalent, key selection criteria include guaranteed 4.1ns max propagation delay at 5V, independent 4-bit/8-bit/16-bit 3-state control via four OE inputs, and MIL-STD-883-compliant industrial temperature operation (–40°C to +85°C).
Technical Context
The 74FCT162244CTPAG implements four independent 4-bit non-inverting buffers, each with dedicated active-low 3-state enable (1OE–4OE). Its 0.5µm CMOS process delivers low ground bounce (<0.6V VOLP) and controlled output fall times without external termination for ≤200pF loads.
All inputs feature hysteresis (100mV typical) for enhanced noise immunity. Output skew is guaranteed ≤0.5ns across same-package outputs, supporting synchronous signal distribution in timing-critical bus architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-rail operation compatible with legacy TTL and 5V CMOS systems |
| Propagation Delay | 4.1ns max (tPLH/tPHL, CL=50pF) - enables >200MHz bus operation with deterministic timing margins |
| Output Drive | ±24mA (industrial) - drives heavy capacitive loads and multiple TTL inputs without fanout limitation |
| Input Hysteresis | 100mV typical - rejects high-frequency noise on address/control lines in electrically noisy industrial environments |
| Operating Temp | –40°C to +85°C - qualified for extended industrial applications including factory automation and telecom infrastructure |
| Output Skew | ≤0.5ns - ensures simultaneous switching of grouped outputs for clean parallel data transfer |
| Quiescent ICC | 500µA max - minimizes standby power in always-on embedded controller interfaces |
Pinout & Package
74FCT162244CTPAG is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), 12.5mm × 6.1mm body, 0.5mm pitch, green (RoHS-compliant) variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control of four 4-bit output groups; assertion disables corresponding Y outputs to high-impedance |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Non-inverting data inputs | 16 total inputs mapped 1:1 to respective output banks; hysteresis improves noise margin |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-state buffered outputs | 16 non-inverting outputs with balanced ±24mA drive and controlled edge rates for minimal EMI |
| VCC (Pins 10, 24, 36, 48) | Power supply | Four distributed VCC pins reduce IR drop and improve decoupling effectiveness across wide bus |
| GND (Pins 11, 23, 35, 47) | Ground reference | Four dedicated GND pins minimize ground bounce and support stable 16-bit switching noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Input-to-output signal path aligned left-to-right across package - simplifies PCB routing and reduces trace crossovers |
| Balanced output drivers | Matched ±24mA sink/source capability - eliminates asymmetry-induced timing jitter in bidirectional bus designs |
| Low ground bounce | Typical VOLP < 0.6V at 5V - maintains logic integrity during simultaneous 16-bit switching without external snubbers |
| Hysteresis on all inputs | 100mV threshold hysteresis - rejects transient noise up to 100mV amplitude on control/address lines |
| Shrink packaging | TSSOP-48 footprint (12.5×6.1mm) - saves >40% board area vs. standard SOIC while maintaining 5V compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT162244CPAG | Same 48-pin TSSOP package, identical pinout and electrical specs; differs only in RoHS status (Pb-free vs. leaded) | No functional difference; suitable for legacy rework where Pb-free compliance is not mandated | Select SN74FCT162244CPAG only if Pb-containing assembly is permitted and cost sensitivity outweighs RoHS requirements |
| 74LVCH162244APAG | 3.3V-only supply (1.65–3.6V), lower drive (±24mA @ 3.3V), 5.2ns max tPD - not 5V-tolerant | Requires full 3.3V system redesign; incompatible with 5V buses or mixed-voltage backplanes | Choose 74LVCH162244APAG only in new 3.3V-only designs where voltage scaling justifies longer propagation delay |
Compared with SN74FCT162244CPAG, 74FCT162244CTPAG offers mandatory RoHS compliance without performance trade-offs; versus 74LVCH162244APAG, it preserves 5V interoperability and delivers 1.1ns faster timing - critical for retrofitting legacy industrial hardware.

FAQ
What is the maximum operating temperature range for the 74FCT162244CTPAG?
The 74FCT162244CTPAG is rated for industrial temperature operation from –40°C to +85°C. This range is fully specified and tested per the datasheet's DC and switching characteristics tables, making it suitable for deployment in factory automation, telecom infrastructure, and outdoor industrial enclosures without derating.
Does the 74FCT162244CTPAG support 3.3V logic inputs?
No, the 74FCT162244CTPAG is a 5V-only device with TTL-compatible input thresholds (VIH = 2.0V min, VIL = 0.8V max). It does not support direct 3.3V logic-level inputs without level translation, as its input structure is optimized for 5V VCC operation and lacks 5V-tolerant I/O architecture.
How many independent 3-state control inputs does the 74FCT162244CTPAG have?
The 74FCT162244CTPAG has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a distinct 4-bit output group (1Y1–1Y4, 2Y1–2Y4, etc.), enabling flexible partitioning of 16-bit data paths into 4-bit, 8-bit, or full 16-bit bus segments.
Is the 74FCT162244CTPAG pin-compatible with the 74ABT16244?
Yes, the 74FCT162244CTPAG is a plug-in replacement for the 74ABT16244, sharing identical pinout, function table, and 48-pin TSSOP package. It delivers higher speed (4.1ns vs. ~5.5ns), lower ground bounce, and improved noise immunity while maintaining full logic and mechanical compatibility.
What is the purpose of hysteresis on all inputs of the 74FCT162244CTPAG?
Hysteresis (100mV typical) on all inputs of the 74FCT162244CTPAG increases noise immunity by creating separate HIGH and LOW switching thresholds. This prevents false triggering from slow-rising signals or high-frequency transients - a critical feature for reliable operation in electrically noisy industrial environments like motor drives or PLC cabinets.
