Product details
Overview
74FCT162245CTPAG8 from Renesas Electronics (formerly IDT) is a 16-bit bidirectional transceiver in TSSOP-48 package, operating at 5V with ±24mA industrial drive strength, <4.5ns A↔B propagation delay, and hysteresis-equipped inputs for noise immunity. It enables synchronous bus interfacing between two 16-bit data paths in industrial control backplanes.
For engineers reviewing the 74FCT162245CTPAG8 datasheet, 74FCT162245CTPAG8 pinout, 74FCT162245CTPAG8 application, or 74FCT162245CTPAG8 equivalent, key selection criteria include bidirectional 16-bit bus isolation, 3-state output control via dual OE/DIR pins, industrial temperature range (–40°C to +85°C), and TSSOP-48 footprint compatibility.
Technical Context
The 74FCT162245CTPAG8 implements two independent 8-bit transceiver sections or one unified 16-bit path using separate direction (xDIR) and output enable (xOE) controls per section. Its balanced CMOS output drivers incorporate internal current-limiting resistors to suppress ground bounce (<0.6V typical) and control fall times without external termination.
Input hysteresis (100mV typical) ensures robust noise margin against signal integrity degradation in electrically noisy industrial environments. The device operates exclusively at VCC = 5.0V ±10% and supports TTL-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) while delivering CMOS-level outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-rail operation; no dual-supply or level-shifting capability |
| tPLH / tPHL | ≤4.5ns (A↔B) - enables high-speed synchronous bus bridging up to ~220MHz clock-equivalent data rates |
| IODL / IODH | ±24mA (industrial) - sufficient drive strength for unterminated stubs on 50Ω-impedance PCB traces |
| VOL / VOH | ≤0.55V @ 24mA / ≥2.4V @ –24mA - meets TTL input compatibility and CMOS logic level requirements |
| tPZH / tPHZ | ≤4.4ns / ≤4.0ns - fast output enable/disable supports dynamic bus arbitration with minimal latency |
| VIN Hysteresis | 100mV typical - rejects >100mV of common-mode noise on control and data lines |
| ICC Quiescent | ≤500µA - low static power draw suitable for always-on industrial interface modules |
Pinout & Package
TSSOP-48 package (4.4mm × 9.7mm body, 0.5mm pitch), thermally enhanced with exposed pad (not electrically connected), RoHS-compliant and green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control inputs (active HIGH) | Determines data flow direction per 8-bit section: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output enable inputs (active LOW) | Disables both ports to high-impedance state when asserted; overrides DIR control |
| 1A1–1A8, 2A1–2A8 | Port A I/O terminals | 8-bit bidirectional data interface for Bus A; internally terminated with hysteresis |
| 1B1–1B8, 2B1–2B8 | Port B I/O terminals | 8-bit bidirectional data interface for Bus B; matched drive strength to Port A |
| VCC (Pins 11, 24, 37, 48) | Power supply | Four dedicated VCC pins reduce IR drop and improve switching noise immunity across wide bus |
| GND (Pins 12, 23, 25, 36, 47) | Ground reference | Five GND pins provide low-inductance return paths for all 16 bidirectional drivers |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA output drive | Eliminates need for external series termination resistors on 50Ω PCB traces |
| Integrated input hysteresis (100mV) | Prevents metastability and chatter on slow-rising or noisy control/data signals |
| Low ground bounce (<0.6V typical) | Enables reliable multi-bit switching without system-level power rail collapse |
| Independent 8-bit section control | Allows simultaneous A↔B and B↔A transfers on separate 8-bit sub-buses |
| Industrial temperature range support | Guaranteed operation from –40°C to +85°C without derating or thermal management |
Applications
| Industrial Backplane Interface | Legacy Bus Extender |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC164245DGGR | 3.3V-only supply, ±24mA drive, 1.8V–3.3V I/O tolerance, no hysteresis | Requires level-shifting for 5V systems; unsuitable for legacy TTL buses | Select only for new 3.3V designs with mixed-voltage I/O; not a drop-in replacement |
| 74FCT16245CTPAG8 | Same family, identical pinout and function but lacks independent 8-bit DIR/OE control (single DIR/OE for all 16 bits) | Less flexible bus partitioning; cannot support concurrent A→B and B→A transfers | Choose when simplified control logic suffices and cost is prioritized over configurability |
Compared with SN74ALVC164245DGGR and 74FCT16245CTPAG8, the 74FCT162245CTPAG8 uniquely supports per-octet direction and enable control-enabling finer-grained bus arbitration and mixed-direction data flow in space-constrained industrial controllers.

FAQ
What is the operating temperature range for the 74FCT162245CTPAG8?
The 74FCT162245CTPAG8 is rated for industrial temperature operation from –40°C to +85°C. This range is guaranteed under VCC = 5.0V ±10% and applies to all DC and AC specifications including propagation delay, drive strength, and noise margin. It does not support extended military ranges (–55°C to +125°C) - those require the 54FCT162245T variant in CERPACK packaging.
Does the 74FCT162245CTPAG8 support 3.3V logic levels?
No, the 74FCT162245CTPAG8 operates exclusively at 5.0V ±10% and is not 3.3V-tolerant. Its inputs meet TTL thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V), and outputs swing rail-to-rail between 0V and 5V. Applying 3.3V signals to its inputs may result in marginal logic recognition; connecting it directly to 3.3V systems requires level translation circuitry.
How many independent transceiver sections does the 74FCT162245CTPAG8 contain?
The 74FCT162245CTPAG8 contains two independent 8-bit bidirectional transceiver sections (labeled Section 1 and Section 2), each with dedicated direction (1DIR/2DIR) and output enable (1OE/2OE) controls. This architecture allows concurrent A→B and B→A data transfers on separate octets - a key differentiator from single-control 16-bit variants like the 74FCT16245CTPAG8.
What is the maximum capacitive load the 74FCT162245CTPAG8 can drive reliably?
The 74FCT162245CTPAG8 is characterized for CL = 50pF in switching tests, and its balanced output drivers maintain specified timing (tPLH/tPHL ≤ 4.5ns) and waveform integrity (VOLP < 0.6V) up to this load. Driving >50pF may increase propagation delay and ground bounce; for heavier loads, verify timing margins using the device's output impedance model and PCB trace characteristics.
Is the 74FCT162245CTPAG8 pin-compatible with the 74FCT16245CTPAG8?
Yes, the 74FCT162245CTPAG8 and 74FCT16245CTPAG8 share identical TSSOP-48 pinouts and package dimensions. However, their functional pin assignments differ: the 74FCT162245CTPAG8 uses Pins 1/2 (1DIR/1OE) and Pins 47/48 (2DIR/2OE), whereas the 74FCT16245CTPAG8 consolidates control onto Pins 1/2 only. PCB layout reuse is possible only if the design accommodates unused control pins as NC or tied-off.
