Product details
Overview
PI74FCT162245ATVE 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 high-noise-margin industrial backplane interfaces.
For engineers reviewing the PI74FCT162245ATVE datasheet, PI74FCT162245ATVE pinout, PI74FCT162245ATVE application, or PI74FCT162245ATVE equivalent, key selection criteria include its balanced drive strength, low-VOLP performance, 48-pin SSOP mechanical compatibility, and direction-controlled 3-state operation in mixed-voltage bus bridging systems.
Technical Context
This device implements dual independent 8-bit bidirectional transceivers within a single 48-pin SSOP package, each side (A/B) featuring identical I/O structures with shared direction (DIR) and output enable (OE) controls per group. Its ±24mA drive capability ensures robust signal integrity across terminated and unterminated traces up to 500Ω load.
The transceiver uses Fast CMOS technology with hysteresis on all inputs (100mV typical), operates over –40°C to +85°C ambient, and maintains Hi-Z outputs when OE is HIGH - enabling hot-swap-safe bus isolation without external pull-ups or termination resistors in most applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with standard TTL/CMOS logic rails and eliminates need for level-shifting in 5V systems |
| IO Drive | ±24mA - balanced sourcing/sinking enables clean edge rates and reduced EMI in high-speed bus environments |
| VOLP (Ground Bounce) | <0.6V typical at VCC=5V, TA=25°C - minimizes noise coupling into shared ground planes during simultaneous switching |
| tPHL Propagation Delay | 1.5–7.0ns (CL=50pF, RL=500Ω) - supports >100MHz bus toggle rates with deterministic timing margins |
| Input Hysteresis | 100mV - improves noise immunity on slow-rising or noisy control lines like DIR/OE in industrial settings |
| Operating Temperature | –40°C to +85°C - qualified for extended-temperature industrial and telecom equipment deployment |
| Package | 48-pin SSOP (300-mil wide, V code) - surface-mount footprint compatible with automated assembly and IPC-7351B land patterns |
Pinout & Package
PI74FCT162245ATVE is housed in a 48-pin plastic SSOP (Shrink Small Outline Package), 300-mil body width, with 0.025" lead pitch and gull-wing terminations. The package is Pb-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input | Determines data flow direction per 8-bit group: LOW = B→A, HIGH = A→B; enables independent bidirectional operation of two sub-buses |
| 1OE, 2OE | Output Enable (Active LOW) | When HIGH, places both A and B ports in high-impedance state - essential for bus arbitration and multi-drop topology support |
| 1A0–1A7, 2A0–2A7 | Side A I/O Terminals | 8-bit bidirectional data interface for Bus A; function as inputs or 3-state outputs depending on DIR/OE states |
| 1B0–1B7, 2B0–2B7 | Side B I/O Terminals | 8-bit bidirectional data interface for Bus B; electrically matched to Side A for symmetrical signal integrity |
| VCC (Pins 7, 22, 37, 46) | Power Supply | Four dedicated VCC pins reduce IR drop and improve decoupling effectiveness across the 48-pin layout |
| GND (Pins 6, 11, 26, 31, 41, 47) | Ground Reference | Six GND pins provide low-inductance return paths and minimize ground bounce during simultaneous output switching |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drivers | Enables matched rise/fall times and controlled edge rates without external series resistors - simplifies PCB routing and reduces component count |
| Low Ground Bounce (<0.6V) | Minimizes voltage perturbation on shared ground nets during high-current switching - critical for mixed-signal system stability |
| Hysteresis on All Inputs | 100mV input threshold margin rejects transient noise on DIR/OE control lines in electrically noisy industrial enclosures |
| 48-Pin SSOP Mechanical Compatibility | Standard 300-mil SSOP footprint allows direct replacement of legacy 74FCT/74ACT transceivers without board redesign |
| Wide Operating Temperature Range | –40°C to +85°C qualification supports deployment in uncontrolled environments such as outdoor base stations and factory-floor controllers |
Applications
| Industrial Backplane Interconnect | Legacy Bus Bridging |
|---|---|

IC Role / Device Role / Timing Role: Bidirectional data translator between CPU local bus and expansion slot peripherals, managing direction and isolation under software control. Use Value: ±24mA drive and <0.6V VOLP ensure reliable data transfer at 20+ MHz without added termination or shielding - reducing BOM cost and board area. | Use Scenario: Interfacing modern microcontrollers to legacy ISA or VMEbus peripherals operating at 5V logic levels. IC Role / Device Role / Timing Role: Voltage- and protocol-transparent bus buffer that isolates timing domains while preserving signal integrity across mismatched loading conditions. Use Value: Dual 8-bit configuration allows independent control of address/data lanes, enabling precise timing alignment and avoiding bus contention during reset sequences. |
| Telecom Line Card Interface | Test Equipment Data Path |
Use Scenario: Routing high-speed configuration and status data between FPGA-based control plane and ASIC-based datapath on carrier-grade line cards. IC Role / Device Role / Timing Role: Synchronous bidirectional transceiver synchronizing control register reads/writes between clock domains with minimal skew (0.5ns max). Use Value: Matched propagation delay (1.5–7.0ns) and low output skew guarantee setup/hold compliance across temperature and voltage corners - eliminating timing closure risk. | Use Scenario: Reconfigurable signal path in automated test equipment where DUT interface voltage levels and bus widths vary per test program. IC Role / Device Role / Timing Role: Programmable bus extender supporting dynamic reassignment of A/B ports as input or output under host controller command. Use Value: Independent DIR/OE per 8-bit group enables real-time reconfiguration of 16-bit paths into two independent 8-bit channels - increasing test parallelism and throughput. |
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 but faster speed grade (C-grade: tPHL ≤4.1ns vs. T-grade ≤7.0ns) | Required for systems demanding tighter timing margins at >50MHz bus toggle rates | Select C-grade only if propagation delay budget is constrained; otherwise T-grade offers optimal cost/performance balance |
| SN74LVCH162245ADGGR | 3.3V-only supply (1.65–3.6V), lower drive (±24mA still supported), different pinout (48-pin TSSOP, not SSOP) | Used in mixed-voltage systems where 3.3V core logic interfaces to 5V peripherals via level translation | Not a drop-in replacement due to voltage incompatibility and package mismatch; requires schematic and layout changes |

FAQ
What is the maximum recommended capacitive load for PI74FCT162245ATVE outputs?
The device is characterized with CL = 50pF and RL = 500Ω in switching specifications. While not explicitly rated for higher loads, sustained operation beyond 75pF may degrade tPHL/tPLH timing and increase VOLP. For loads >60pF, verify signal integrity using actual board trace capacitance and consider adding series damping resistors near drivers.
Can PI74FCT162245ATVE operate with VCC = 4.5V?
Yes - the device is specified for VCC = 5.0V ±10%, meaning 4.5V to 5.5V is within its guaranteed operating range. At 4.5V, VOH remains ≥2.4V (IOH = –24mA) and VOL stays ≤0.55V (IOL = 24mA), maintaining full TTL/CMOS compatibility without derating.
Does PI74FCT162245ATVE support live insertion?
No - unlike the PI74FCT16245T variant, the PI74FCT162245T/ATVE does not feature power-off disable outputs. Its outputs enter Hi-Z only when OE is asserted; they do not automatically tri-state during VCC ramp-down, so live insertion requires external circuitry or system-level sequencing control.
How many GND pins does PI74FCT162245ATVE have, and why are they distributed?
It has six GND pins (pins 6, 11, 26, 31, 41, 47) placed across the package to minimize ground loop inductance and distribute return current paths. This layout reduces simultaneous switching noise and keeps VOLP below 0.6V even with all 16 outputs switching at once - a key requirement for high-density backplane designs.
