Product details
Overview
74FCT163245APAG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit bidirectional transceiver with dual 8-bit operation capability, tPLH/tPHL ≤ 4.6 ns at VCC = 3.3V, rail-to-rail output swing, and industrial temperature range (–40°C to +85°C). It serves as a bus interface buffer between asynchronous A- and B-side data buses in memory expansion and FPGA I/O bridging applications.
For engineers reviewing the 74FCT163245APAG datasheet, 74FCT163245APAG pinout, 74FCT163245APAG application, or 74FCT163245APAG equivalent, key selection criteria include bidirectional flow control via xDIR/xOE, 3.3V-only supply with 5V-tolerant inputs, low ground bounce (0.3V typ.), and SSOP-48 package compatibility for high-density PCB layouts.
Technical Context
The 74FCT163245APAG implements two independent 8-bit transceiver sections controlled by separate DIR/OE pins per section, enabling flexible bus segmentation. Its dual-metal CMOS process ensures sub-5 ns propagation delay and < 250 ps output skew across all 16 outputs under matched load conditions.
All inputs feature hysteresis (150 mV typ.) for noise immunity, while I/O pins support 3.3V logic levels and tolerate 5V inputs-critical for mixed-voltage system interfacing. Output drive strength is ±60 mA (sink/source), with VOH ≥ 2.4V at IOH = –8mA and VOL ≤ 0.4V at IOL = 24mA under industrial VCC = 3.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports extended industrial supply tolerance without level-shifting circuitry |
| Propagation Delay | tPLH/tPHL ≤ 4.6 ns - enables reliable 200+ MHz bus handshaking in synchronous systems |
| Output Skew | tSK(o) ≤ 0.5 ns - ensures deterministic timing alignment across all 16 bits for parallel data capture |
| Input Hysteresis | 150 mV typ. - improves noise margin against EMI in noisy industrial environments |
| IOH/IOL Drive | –60 mA / +90 mA - drives standard TTL loads and short traces without external buffers |
| ESD Rating | > 2000V HBM - meets MIL-STD-883 Class 3A handling requirements for production assembly |
| Quiescent ICC | ≤ 10 µA - enables ultra-low static power in always-on bus monitoring circuits |
Pinout & Package
74FCT163245APAG is housed in a 48-pin Shrink Small Outline Package (SSOP), 0.635 mm pitch, 12.0 × 7.5 mm body size, with exposed pad not present. Pin numbering follows standard SSOP top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Configures data flow direction per 8-bit section: LOW = B→A, HIGH = A→B |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables both A/B ports to high-impedance when HIGH; overrides DIR control |
| 1A1–1A8, 2A1–2A8 | Side A I/O Terminals | Bi-directional data lines for first/second 8-bit bus segment; 5V-tolerant inputs |
| 1B1–1B8, 2B1–2B8 | Side B I/O Terminals | Bi-directional data lines for second/first 8-bit bus segment; rail-to-rail CMOS outputs |
| VCC (Pins 11, 24, 36, 47) | Power Supply | Four dedicated VCC pins reduce IR drop and improve switching noise suppression |
| GND (Pins 12, 25, 37, 48) | Ground Reference | Four GND pins minimize ground bounce and ensure stable reference for all I/O |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Enables split-bus operation: e.g., A1–A8 ↔ B1–B8 and A9–A16 ↔ B9–B16 can be managed separately |
| Rail-to-rail output swing | VOH ≥ VCC–0.2V and VOL ≤ 0.2V at light load - maximizes noise margin in 3.3V systems |
| 5V-tolerant inputs | Accepts 0–5.5V input signals on all non-I/O pins - simplifies interface to legacy 5V peripherals |
| Low ground bounce (0.3V typ.) | Reduces simultaneous switching noise that could corrupt adjacent signal integrity or analog sections |
| 0.5 µm CMOS process | Delivers high speed with low static power (0.4 µW typ.) - suitable for thermally constrained industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVCH163245ADGGR | Lower drive (±24 mA), wider VCC range (1.65–3.6V), no 5V-tolerant inputs | Suitable for battery-powered portable gear but not mixed-voltage backplanes | Select when ultra-low power (< 1 µA ICC) and single-supply flexibility outweigh 5V interface needs |
| 74ALVC163245PW | Higher speed (tPD ≤ 3.2 ns), same 3.3V supply, 5V-tolerant inputs, TSSOP-48 package | Better suited for high-frequency test instrumentation requiring tighter timing margins | Choose when propagation delay budget is ≤3.5 ns and board layout allows TSSOP footprint |
Compared with SN74LVCH163245ADGGR and 74ALVC163245PW, the 74FCT163245APAG delivers superior 5V-tolerance and higher drive strength at modest speed-making it optimal for industrial backplane and legacy peripheral interfacing where robustness trumps peak frequency.

FAQ
What is the maximum clock rate supported by the 74FCT163245APAG in a synchronous bus application?
The 74FCT163245APAG does not contain internal clock circuitry and is an asynchronous transceiver. Its usable data rate depends on propagation delay and system timing margins: with tPLH/tPHL ≤ 4.6 ns and tSK(o) ≤ 0.5 ns, it reliably supports bus handshaking up to 200 MHz in well-terminated, low-skew layouts. The 74FCT163245APAG must be used with external control signals (xDIR/xOE) synchronized to the host system clock.
Does the 74FCT163245APAG support hot-plug or live-insertion operation?
The 74FCT163245APAG features power-up/down high-impedance protection and bus-hold capability is not integrated. While its absolute maximum ratings include VTERM(4) = –0.5V to VCC+0.5V on I/O pins, true hot-plug operation requires external series resistors and sequencing control. The 74FCT163245APAG itself does not guarantee glitch-free insertion under live bus conditions without supporting circuitry.
Can the 74FCT163245APAG be used with a 2.5V supply voltage?
No. The 74FCT163245APAG is specified only for VCC = 2.7V to 3.6V. At 2.5V, VIH minimum (2.0V) and VOH performance degrade beyond guaranteed limits, and output drive falls below required levels. Operation below 2.7V violates the device's electrical specifications and is not supported. The 74FCT163245APAG must be powered within its rated supply range.
How many 74FCT163245APAG devices can be cascaded on a single bus without signal integrity degradation?
Signal integrity depends on trace length, termination, and capacitive loading-not device count alone. Each 74FCT163245APAG adds ≤6 pF input capacitance (CIN) and ≤8 pF output capacitance (COUT). For a 50 pF total load budget, up to eight devices may be placed on one net-but practical limits are governed by flight time, reflection, and skew accumulation. The 74FCT163245APAG is intended for point-to-point or stub-based topologies, not multidrop buses.
Is the 74FCT163245APAG RoHS-compliant and lead-free?
Yes. The "PAG" suffix denotes a lead-free, RoHS-compliant Shrink Small Outline Package (SSOP) per Renesas' 2009 ordering information update. The 74FCT163245APAG meets JEDEC J-STD-609 Category 1 marking requirements and contains no intentionally added lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
