Product details
Overview
PI74FCT162245CTVE from Pericom Semiconductor is a 16-bit bidirectional CMOS transceiver with ±24mA balanced output drivers, 5V supply operation, and 48-pin SSOP (V) package. It enables asynchronous two-way data bus communication between A- and B-side buses, supports dual 8-bit or single 16-bit configuration via DIR/OE controls, and reduces ground bounce (<0.6V typical) for noise-sensitive backplane and motherboard interfaces.
For engineers reviewing the PI74FCT162245CTVE datasheet, PI74FCT162245CTVE pinout, PI74FCT162245CTVE application, or PI74FCT162245CTVE equivalent, key selection criteria include its balanced drive strength, low-VOLP performance, direction-controlled 3-state operation, and compatibility with 5V TTL/CMOS logic families in high-density PCB layouts.
Technical Context
This device implements dual independent 8-bit bidirectional transceivers within a single 48-pin SSOP package, using separate DIR and OE inputs per side to configure data flow direction and enable/disable outputs. Its output buffers integrate on-die current-limiting resistors to control edge rates, minimizing simultaneous switching noise without external termination.
The transceiver operates across –40°C to +85°C ambient, with guaranteed VIH/VIL thresholds (2.0V/0.8V), hysteresis (100mV), and propagation delays ≤4.1ns (max) under CL=50pF/RL=500Ω loading - enabling reliable timing in high-speed parallel bus systems such as ISA, PCI-X stubs, and memory expansion interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with standard 5V logic rails and legacy industrial power domains |
| Output Drive | ±24mA - balanced sourcing/sinking ensures symmetrical signal integrity on shared buses |
| Propagation Delay | ≤4.1ns max (A↔B) - supports >200MHz bus toggle rates in point-to-point configurations |
| Ground Bounce | <0.6V typical at VCC=5V - reduces noise coupling into adjacent analog or clock traces |
| Input Hysteresis | 100mV - improves noise immunity on slow-rising or unterminated control lines (DIR/OE) |
| Operating Temp | –40°C to +85°C - qualified for industrial temperature range without derating |
| Package | 48-pin SSOP (300-mil wide, V code) - surface-mount footprint with 0.635mm pitch for automated assembly |
Pinout & Package
48-pin plastic SSOP (300-mil wide), JEDEC MO-153 compliant, Pb-free and RoHS-compliant. Pin 1 marked by notch or dot; pin numbering follows standard counter-clockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input | Active-HIGH logic selects A→B (H) or B→A (L); enables dual 8-bit mode when used independently |
| 1OE, 2OE | Output Enable Input | Active-LOW disables both A and B ports to Hi-Z; allows hot-swap isolation of bus segments |
| 1A0–1A7, 2A0–2A7 | Side A I/O Terminals | Bi-directional data pins for first and second 8-bit bus segment; internally buffered with controlled slew |
| 1B0–1B7, 2B0–2B7 | Side B I/O Terminals | Bi-directional data pins mirroring Side A; electrically isolated but share VCC/GND planes |
| VCC (Pins 7, 22, 37) | Power Supply | Three dedicated VCC pins reduce IR drop and improve decoupling effectiveness across wide bus |
| GND (Pins 6, 21, 36) | Ground Reference | Three GND pins minimize ground loop inductance and stabilize reference for all 16 drivers |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drivers | Equal sourcing/sinking capability eliminates DC bias on terminated buses and prevents signal asymmetry |
| On-Die Edge Rate Control | Integrated current-limiting resistors suppress ground bounce and undershoot without external components |
| Hysteresis on All Inputs | 100mV input threshold margin rejects EMI-induced glitches on DIR/OE control lines in noisy environments |
| Low Quiescent ICC | 0.1µA typical ICC at VCC=5V - enables low-power standby in battery-backed or always-on subsystems |
| Wide Operating Temperature | –40°C to +85°C ambient rating - supports deployment in uncontrolled industrial enclosures |

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 |
|---|---|---|---|
| SN74FCT162245CTPVR | TI variant with identical ±24mA drive, same 48-pin TSSOP (P) package; slightly higher ICC (1.5mA vs 0.7mA typ) | Same functional role but optimized for TI-centric BOMs; lacks Pericom's specific ground-bounce characterization | Select when TI supply chain alignment or existing TI design reuse is prioritized |
| 74ALVC162245PW | NXP part rated for 3.3V only; ±24mA drive at 3.3V, not 5V; different pinout (TSSOP-48, no SSOP option) | Requires level translation for 5V systems; unsuitable for direct replacement without voltage adaptation | Choose only for new 3.3V-only designs where lower VCC simplifies power architecture |
Compared with SN74FCT162245CTPVR and 74ALVC162245PW, PI74FCT162245CTVE offers verified 5V operation with documented <0.6V ground bounce, SSOP packaging for thermal and routing advantages, and tighter ICC control - making it optimal for industrial 5V backplane applications requiring noise resilience and legacy compatibility.

FAQ
What is the maximum operating frequency supported by PI74FCT162245CTVE?
The device does not specify a maximum clock frequency, but its 4.1ns maximum propagation delay (A↔B) under 50pF/500Ω load implies reliable operation up to ~200MHz for toggling single-bit patterns. System-level frequency limits depend on trace length, termination, and bus loading - actual bus throughput must be validated with IBIS simulation or lab measurement.
Can PI74FCT162245CTVE operate with mixed-voltage interfaces (e.g., 3.3V inputs driving a 5V bus)?
No. PI74FCT162245CTVE is strictly a 5V device: VIH minimum is 2.0V, but inputs are not 5V-tolerant when VCC = 5V. Driving it with 3.3V logic may result in marginal or non-functional HIGH recognition. For mixed-voltage systems, use a dedicated level translator upstream of this transceiver.
Does PI74FCT162245CTVE support hot-plug insertion?
It supports live insertion only in contexts where power sequencing is controlled: the outputs enter Hi-Z when OE is HIGH, but the device itself lacks true power-off disable (a feature present in PI74FCT16245T, not the 162245T). VCC must remain stable during insertion; applying VCC after signal connection risks latch-up.
Are the DIR and OE pins 5V-tolerant when pulled to 5V while VCC is off?
No. Absolute maximum ratings specify input voltage range as –0.5V to +7.0V only when VCC is applied. With VCC = 0V, applying 5V to DIR or OE violates the "Supply Voltage to Ground Potential (Inputs & VCC Only)" limit and risks permanent damage due to parasitic diode conduction into unpowered circuitry.
