Product details
Overview
74FCT163244APAG8 from Renesas Electronics is a 3.3V CMOS 16-bit non-inverting buffer/line driver with quad-nibble/dual-byte/16-bit selectable 3-state control, rail-to-rail output swing, <250ps output skew, and industrial temperature range (–40°C to +85°C). It serves as a level-translating bus interface in mixed 3.3V/5V systems, e.g., connecting 5V logic to a 3.3V backplane.
For engineers reviewing the 74FCT163244APAG8 datasheet, 74FCT163244APAG8 pinout, 74FCT163244APAG8 application, or 74FCT163244APAG8 equivalent, key selection criteria include its 3.3V ±0.3V supply operation, 50mA output drive capability, input hysteresis for noise immunity, low ground bounce (0.3V typ.), and compatibility with SSOP-48 package layout constraints.
Technical Context
The 74FCT163244APAG8 implements four independent 4-bit non-inverting buffers, each with dedicated active-low 3-state enable (xOE), enabling flexible bus segmentation. Its dual-metal CMOS process delivers high-speed propagation (tPLH/tPHL ≤ 4.8ns at CL=50pF) while maintaining CMOS static power (0.4μW typ.).
All inputs accept 3.3V or 5V logic levels, allowing direct interfacing with legacy TTL or LVTTL components without external level shifters. Outputs drive ±60mA and support rail-to-rail swing, ensuring robust noise margin across VCC = 2.7V–3.6V extended range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports both normal (3.3V±0.3V) and extended supply tolerance for system-level voltage margining |
| tPLH / tPHL | ≤4.8ns at CL=50pF - enables reliable timing in high-speed parallel bus interfaces up to ~100MHz |
| IOL / IOH | ±60mA - drives heavy capacitive loads (e.g., long traces, multiple inputs) without signal degradation |
| tSK(o) | <0.5ns - ensures tight skew control critical for synchronous data capture across all 16 outputs |
| VIH/VIL (5V-tolerant) | VIH up to 5.5V, VIL down to –0.5V - allows direct connection to 5V logic without level-shifting circuitry |
| Input Hysteresis | 150mV - suppresses false triggering from slow-rising or noisy input signals on shared control lines |
Pinout & Package
74FCT163244APAG8 is housed in a 48-pin Shrink Small Outline Package (SSOP), measuring 15.9mm × 7.5mm × 2.3mm, with 0.635mm lead pitch and gull-wing leads compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Each controls one 4-bit group (Y1–Y4); enables independent bus segment isolation |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data inputs | Non-inverting inputs for corresponding output groups; 5V-tolerant |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-state buffered outputs | Drive bidirectional buses with high sink/source current and rail-to-rail swing |
| VCC (Pins 10, 24, 39, 48) | Power supply | Four distributed VCC pins minimize IR drop and improve high-frequency decoupling |
| GND (Pins 9, 23, 38, 47) | Ground reference | Four dedicated GND pins reduce ground bounce and maintain signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant inputs | Accepts 5V logic signals while operating at 3.3V VCC - eliminates need for external translators in mixed-voltage systems |
| Rail-to-rail output swing | VOH ≥ VCC–0.2V, VOL ≤ 0.2V at light load - maximizes noise margin for reliable logic-level detection |
| Low ground bounce (0.3V typ.) | Minimizes simultaneous switching noise that could corrupt adjacent signals or cause timing violations |
| Flow-through pinout | Inputs and outputs arranged on opposite sides of package - simplifies PCB routing and reduces trace crossovers |
| Hysteresis on all inputs | 150mV threshold window - rejects sub-threshold noise on enable and data lines without external RC filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | 3.3V-only inputs (not 5V-tolerant); lower drive (24mA); smaller TSSOP-48 package (12.5×6.1mm) | Suitable only in pure 3.3V systems; requires external level shifters for 5V interfacing | Select when board space is constrained and no 5V logic is present |
| 74ALVCH16244DGG | Higher speed (tPD ≤ 3.3ns); same 5V-tolerant inputs; identical SSOP-48 footprint | Better suited for >100MHz bus applications but consumes higher dynamic current | Select when propagation delay is critical and power budget allows +20% ICCD |
Compared with SN74LVC16244ADGGR and 74ALVCH16244DGG, the 74FCT163244APAG8 uniquely balances 5V-tolerant input flexibility, industrial temperature reliability, and low ground bounce-making it optimal for legacy-to-modern voltage translation where signal integrity and robustness outweigh minimal size or speed gains.

FAQ
What is the maximum operating temperature range for the 74FCT163244APAG8?
The 74FCT163244APAG8 is rated for industrial temperature operation from –40°C to +85°C. This range is guaranteed across all electrical specifications including propagation delay, output drive, and 3-state leakage. The device uses thermal design and packaging validated for sustained operation in enclosed control cabinets and under-hood automotive environments without derating.
Does the 74FCT163244APAG8 support 5V logic inputs while powered at 3.3V?
Yes, the 74FCT163244APAG8 supports 5V-tolerant inputs: VIH can reach 5.5V and VIL can go as low as –0.5V, even when VCC is 3.3V. This is confirmed in the DC Electrical Characteristics table and enables direct interfacing with 5V TTL or LVTTL sources without external level shifters-critical for backward-compatible system upgrades.
What package type is used for the 74FCT163244APAG8 and what are its key mechanical features?
The 74FCT163244APAG8 uses a 48-pin Shrink Small Outline Package (SSOP) with "PAG" suffix. It measures 15.9mm × 7.5mm × 2.3mm, has 0.635mm lead pitch, gull-wing leads, and RoHS-compliant green molding compound. Four VCC and four GND pins provide low-inductance power distribution essential for noise-sensitive bus drivers.
How does the 74FCT163244APAG8 manage simultaneous switching noise?
The 74FCT163244APAG8 limits ground bounce to 0.3V typical via optimized output stage design and distributed grounding (four GND pins). Its low ICCZ quiescent current (≤10μA) and controlled edge rates further reduce dI/dt-induced noise-verified by measurement in the datasheet's DC Electrical Characteristics section under "Low Ground Bounce."
Can the 74FCT163244APAG8 be used in a single 16-bit mode or only in nibble/byte configurations?
The 74FCT163244APAG8 supports all three modes: quad-nibble (four independent 4-bit groups), dual-byte (two 8-bit groups), or full 16-bit (all outputs enabled simultaneously) via its four active-low OE inputs (1OE–4OE). The functional block diagram and function table confirm this configurability, making it adaptable to diverse bus architectures without redesign.
