Product details

Overview

PI74FCT16245CTVEX from Pericom Semiconductor is a 16-bit bidirectional CMOS transceiver in 48-pin SSOP (V) package, operating at 5V ±10%, with ±32mA/64mA high-current drive, power-off disable for live insertion, and <1.0V typical ground bounce. It enables asynchronous bus-to-bus communication in backplane and industrial control systems.

For engineers reviewing the PI74FCT16245CTVEX datasheet, PI74FCT16245CTVEX pinout, PI74FCT16245CTVEX application, or PI74FCT16245CTVEX equivalent, key selection criteria include direction-controlled bidirectional data flow, 4.1ns max propagation delay (16245C grade), Hi-Z output enable, and SSOP-48 mechanical compatibility with legacy FCT bus interfaces.

Technical Context

This device implements dual 8-bit or single 16-bit bidirectional data transfer via independent DIR/OE controls per side pair. Its TTL-compatible inputs feature hysteresis (100mV), and outputs support live insertion via power-off disable - active when VCC = 0V and I_OFF ≤ ±100µA.

Designed for low-noise backplane driving, it delivers 64mA sink / –32mA source capability at V_CC = 4.5V, with propagation delay as low as 1.5ns (min) and 4.1ns (max, C-grade), and output skew limited to 0.5ns across all 16 bits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	4.5V–5.5V: Ensures compatibility with standard 5V TTL/CMOS logic rails and tolerates supply ripple without functional degradation.
I_OH/I_OL	–32mA / 64mA: Enables direct drive of heavy capacitive loads (e.g., >50pF buses) without external buffers.
t_PHL/t_PLH (max)	4.1ns @ CL=50pF: Supports >200MHz bus toggle rates in point-to-point or lightly loaded stubbed topologies.
V_OLP (typ)	<1.0V @ V_CC=5V: Reduces ground bounce-induced false triggering in multi-transceiver backplane environments.
Power-off Disable	I_OFF ≤ ±100µA @ V_CC=0V: Allows safe hot-plug insertion into powered backplanes without bus contention or latch-up risk.
Input Hysteresis	100mV: Improves noise immunity on slow-rising or noisy control lines (e.g., OE/DIR from microcontroller GPIO).
C_IN/C_OUT	4.5pF / 5.5pF: Minimizes capacitive loading on upstream drivers and reduces signal integrity impact in dense PCB layouts.

Pinout & Package

Package: 48-pin plastic SSOP (300-mil width, V code), RoHS-compliant, body dimensions 15.75mm × 7.49mm × 2.4mm, 0.635mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction Control Input (active-HIGH)	Configures data flow direction per 8-bit side: HIGH = A→B, LOW = B→A; supports independent side operation.
1OE, 2OE	Output Enable Input (active-LOW)	Places corresponding A/B port outputs in Hi-Z state when HIGH; enables bus sharing and isolation.
1A0–1A7, 2A0–2A7	Side A I/O Terminals	Bidirectional data pins for Bus A; internally connected to transceiver core with controlled drive strength.
1B0–1B7, 2B0–2B7	Side B I/O Terminals	Bidirectional data pins for Bus B; electrically matched to Side A for symmetrical timing and drive.
V_CC (Pins 7, 22, 37)	Power Supply	Three dedicated V_CC pins reduce IR drop and improve simultaneous switching noise margin across 16-bit width.
GND (Pins 4, 19, 34)	Ground Reference	Three GND pins provide low-inductance return paths, critical for maintaining <1.0V ground bounce spec.

Key Features

Feature	Design Value
Live-insertion support	Power-off disable ensures zero current injection and no bus contention during hot-swap into powered backplanes.
High-current drive asymmetry	64mA sink / –32mA source optimizes for common bus termination schemes where stronger pull-down prevents floating states.
Low ground bounce	Typical V_OLP < 1.0V enables reliable operation in multi-transceiver systems without added decoupling complexity.
Control pin hysteresis	100mV input hysteresis rejects noise on DIR/OE lines, preventing metastability during slow or noisy control transitions.
C-grade speed bin	4.1ns max propagation delay meets timing-critical applications such as real-time industrial I/O expansion modules.

Applications

Use Scenario: Connecting isolated PLC I/O modules to a central controller via a passive 5V backplane with 16-bit parallel data lanes.

IC Role / Device Role / Timing Role: Bidirectional level-shifting transceiver managing synchronous data exchange between mismatched voltage domains and timing margins.

Use Value: Power-off disable prevents bus corruption during module replacement; 4.1ns delay ensures setup/hold compliance at 25MHz bus clock.

Use Scenario: Extending ISA or VMEbus segments using daughter cards with local memory-mapped peripherals.

IC Role / Device Role / Timing Role: Isolating and buffering address/data/control signals between host and peripheral card while preserving signal integrity.

Use Value: ±32mA/64mA drive compensates for trace capacitance up to 100pF; Hi-Z OE enables dynamic bus arbitration.

Test Equipment Data Path

Automated Test Fixture

Use Scenario: Routing stimulus/response data between FPGA-based pattern generator and DUT interface in ATE systems.

IC Role / Device Role / Timing Role: Reconfigurable data path element enabling bidirectional test vector streaming with sub-5ns timing precision.

Use Value: 0.5ns output skew guarantees deterministic phase alignment across all 16 bits for synchronized sampling.

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
74FCT16245CTPV	Same electrical specs and pinout; manufactured by ON Semiconductor (legacy Fairchild), not Pericom.	No live-insertion power-off disable; I_OFF not characterized - unsuitable for hot-swap backplanes.	Select only for cost-sensitive, fixed-installation systems where board replacement occurs with power off.
SN74ALVC164245DGGR	3.3V-only operation (1.65–3.6V); LVCMOS I/O; 24mA drive; no power-off disable; different pinout (48-TSSOP).	Requires level translation for 5V bus interfacing; lacks ground bounce optimization for high-density backplanes.	Prefer for new 3.3V designs with space-constrained layouts; avoid when interfacing legacy 5V infrastructure.

Compared with 74FCT16245CTPV and SN74ALVC164245DGGR, PI74FCT16245CTVEX uniquely combines 5V operation, live-insertion safety, and sub-1V ground bounce - making it the only choice for field-serviceable industrial backplanes requiring zero-downtime module swaps.

FAQ

Is PI74FCT16245CTVEX pin-compatible with other 48-pin SSOP 16-bit transceivers?

Yes - it shares identical pinout and footprint with PI74FCT16245TV, PI74FCT16245ATV, and PI74FCT162245TV variants. However, drive strength and ground bounce performance differ: PI74FCT16245CTVEX provides –32mA/64mA drive and <1.0V V_OLP, unlike the ±24mA balanced drive of the 162245 series.

What is the maximum bus capacitance supported at 25MHz operation?

At 25MHz with 50% duty cycle and 50pF load (per datasheet test condition), propagation delay remains within 4.1ns spec. For higher capacitance, derate: empirical validation shows stable operation up to 100pF with <10% timing margin loss, assuming proper V_CC/GND decoupling at each SSOP power pin.

Does PI74FCT16245CTVEX support mixed-voltage operation between Side A and Side B?

No - both sides share a single V_CC rail (5V ±10%) and are not level-translating. Side A and Side B operate at identical logic thresholds (VIH = 2.0V, VIL = 0.8V); use external translators like TXB0108 for true 3.3V↔5V bridging.

How does the power-off disable function behave during partial power loss?

When V_CC drops below 0.5V, outputs enter Hi-Z with leakage ≤ ±100µA regardless of OE/DIR state. This prevents back-driving of powered buses. The function is tested per datasheet ICCD and IOFF specs - no external pull-ups or clamps required for safe operation.
