Product details
Overview
PI74FCT162245TVE from Pericom Semiconductor is a 16-bit bidirectional CMOS transceiver in 48-pin SSOP (300-mil) package, designed for asynchronous two-way bus communication between data buses. It features ±24mA balanced output drivers, <0.6V typical ground bounce at 5V/25°C, and dual 8-bit or single 16-bit configuration via independent DIR/OE controls - used in backplane interconnects and high-noise industrial bus interfaces.
For engineers reviewing the PI74FCT162245TVE datasheet, PI74FCT162245TVE pinout, PI74FCT162245TVE application, or PI74FCT162245TVE equivalent, key selection criteria include its low-ground-bounce drive capability, 1.5–7.0 ns propagation delay (A↔B), 48-pin SSOP mechanical compatibility, and support for live-insertion-adjacent system architectures requiring controlled edge rates without external termination.
Technical Context
The PI74FCT162245TVE implements dual independent 8-bit bidirectional transceiver channels (1A/1B and 2A/2B), each with dedicated direction (xDIR) and output enable (xOE) controls. Its ±24mA balanced drivers reduce simultaneous switching noise and eliminate need for external termination resistors in most applications.
It operates across –40°C to +85°C ambient, with VCC = 5.0V ±10%, hysteresis on all inputs for noise immunity, and guaranteed high-impedance outputs when xOE is HIGH. Propagation delay (A↔B) is 1.5–7.0 ns under CL = 50 pF / RL = 500 Ω conditions, and output skew is ≤0.5 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with standard TTL/CMOS logic rails and industrial 5V systems |
| Output Drive | ±24mA - balanced sourcing/sinking enables clean signal integrity on shared buses without overshoot |
| Ground Bounce | <0.6V typical at VCC=5V, TA=25°C - minimizes supply rail disturbance during high-speed switching |
| Propagation Delay | 1.5–7.0 ns (A↔B, CL=50pF) - supports >100 MHz bus toggle rates in point-to-point configurations |
| Input Hysteresis | 100 mV - improves noise margin against EMI in electrically noisy industrial environments |
| Operating Temp | –40°C to +85°C - qualified for extended-temperature industrial control and telecom infrastructure |
| ESD Rating | ±2kV HBM - provides robust handling during board assembly and field service |
Pinout & Package
PI74FCT162245TVE is housed in a 48-pin 300-mil wide plastic SSOP (Package Code V), RoHS-compliant and green-qualified. Pin spacing is 0.025" (0.635 mm), body width 0.300", and lead count includes 24 pins per side with GND/VCC distributed for low-inductance power delivery.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1A0–1A7, 2A0–2A7 | Side A I/O Terminals | 8-bit bidirectional port per channel; function as input or 3-state output based on DIR/OE |
| 1B0–1B7, 2B0–2B7 | Side B I/O Terminals | 8-bit bidirectional port per channel; complementary to Side A with matched timing |
| VCC (Pins 7, 22, 37, 46) | Power Supply | Four dedicated VCC pins reduce IR drop and improve transient response across wide bus |
| GND (Pins 6, 21, 36, 45) | Ground Reference | Four GND pins provide low-inductance return paths for balanced driver currents |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drivers | Enables matched rise/fall times and eliminates need for external series termination on PCB traces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74FCT162245CTVE | Same pinout and function; improved speed grade (4.1 ns max tPHL vs. 7.0 ns) | Better suited for >80 MHz bus toggle rates; identical thermal and noise specs | Select when tighter timing margins or higher-frequency operation is required |
| SN74LVTH162245DGGR | 3.3V-only supply (1.65–3.6V); lower drive (±24mA still, but at 3.3V) | Requires level translation when interfacing with 5V buses; not drop-in compatible | Choose only for new 3.3V-only designs where voltage scaling is mandatory |
Compared with 74FCT162245CTVE, PI74FCT162245TVE offers relaxed timing at lower cost for legacy 5V systems; versus SN74LVTH162245DGGR, it maintains full 5V compatibility and superior noise immunity but lacks 3.3V operation.

FAQ
What is the maximum operating frequency supported by PI74FCT162245TVE?
The device does not specify a maximum clock frequency, but its 1.5–7.0 ns propagation delay (A↔B, CL=50 pF) supports reliable data toggling up to approximately 100 MHz in point-to-point configurations. System-level timing depends on trace length, load capacitance, and termination - actual bus rate must be validated with worst-case setup/hold analysis.
Can PI74FCT162245TVE interface directly with 3.3V logic?
No - PI74FCT162245TVE is a 5V-only device (VCC = 5.0V ±10%). Its inputs tolerate up to 7.0V, but outputs swing rail-to-rail at 5V and are not 3.3V-tolerant. Direct connection to 3.3V CMOS inputs risks overvoltage damage; level-shifting circuitry or a 3.3V-compatible transceiver like SN74LVTH162245 is required.
Does PI74FCT162245TVE support hot-swap or live-insertion?
While PI74FCT162245TVE itself lacks explicit power-off disable (unlike PI74FCT16245T), its ±24mA balanced drivers, low ground bounce (<0.6V), and hysteresis inputs make it robust during controlled hot-swap events in properly designed backplanes. However, full live-insertion capability requires companion power sequencing and bus arbitration - the device alone does not guarantee glitch-free insertion.
How many power and ground pins does PI74FCT162245TVE have in its SSOP-48 package?
The PI74FCT162245TVE in 48-pin SSOP (Package Code V) has four VCC pins (pins 7, 22, 37, 46) and four GND pins (pins 6, 21, 36, 45), distributed across both sides of the package to minimize power delivery inductance and support high-current switching without excessive rail collapse.
