Product details
Overview
PI74FCT162244ATV from Pericom Semiconductor is a 16-bit non-inverting buffer/line driver with balanced ±24mA output drive, designed for high-capacitance backplane and bus interface applications. It features current-limiting output resistors to control edge rate, reducing ground bounce (<0.6V typical) and eliminating need for external termination resistors. Operates at 5V ±10% over –40°C to +85°C.
For engineers reviewing the PI74FCT162244ATV datasheet, PI74FCT162244ATV pinout, PI74FCT162244ATV application, or PI74FCT162244ATV equivalent, key selection criteria include output drive symmetry, low switching noise performance, three-state control flexibility (quad-nibble/dual-byte/16-bit), and TVSOP-48 package compatibility with high-density PCB layouts.
Technical Context
This device implements a flow-through pinout architecture optimized for minimal trace routing complexity in backplane and motherboard designs. Its four independent 4-bit sections each feature dedicated active-low 3-state enable inputs (1OE–4OE), enabling granular bus segmentation and power-aware signal gating.
All inputs include hysteresis (100mV typ.) for noise immunity on slow-rising signals, and outputs are designed with internal current-limiting resistors to constrain di/dt-directly lowering system-level ground bounce and undershoot without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5.0V ±10% - supports standard TTL/CMOS logic rails with margin for industrial voltage variation |
| Output Drive | ±24mA - symmetric sourcing/sinking enables stable driving of unterminated transmission lines |
| Propagation Delay | 1.5–6.5ns (CL = 50pF) - ensures timing compliance in 50MHz+ parallel bus systems |
| Ground Bounce | <0.6V typical at VCC = 5V - reduces risk of false logic transitions during simultaneous switching |
| Input Hysteresis | 100mV - improves noise margin on noisy or slow-slew control signals like board-enable lines |
| Operating Temp | –40°C to +85°C - qualified for industrial and telecom infrastructure environments |
| Input Capacitance | 4.5–6pF - minimizes loading on upstream drivers in fanout-critical applications |
Pinout & Package
PI74FCT162244ATV is housed in a 48-pin TVSOP (Thin Very Small Outline Package), 173 mil wide, with 0.4mm pitch and exposed pad for thermal enhancement. Pin numbering follows standard counter-clockwise layout starting from pin 1 (1OE) at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control per 4-bit section; enables quad-nibble mode for partial bus isolation |
| 1A0–4A3 | Non-inverting input terminals (16 total) | Flow-through mapping aligns inputs directly opposite corresponding outputs for straight PCB routing |
| 1Y0–4Y3 | Non-inverting 3-state outputs (16 total) | Current-limited ±24mA drivers with controlled edge rate; no external termination required |
| VCC (Pins 7, 15, 23, 31, 39) | Power supply | Five distributed VCC pins reduce IR drop and improve power integrity across wide bus |
| GND (Pins 4, 12, 20, 28, 36) | Ground reference | Five GND pins provide low-inductance return paths, critical for minimizing ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drive | Enables matched rise/fall times on unterminated traces, reducing EMI and signal integrity issues |
| Integrated Edge-Rate Control | Internal current-limiting resistors eliminate need for external series resistors on all 16 outputs |
| Low Ground Bounce (<0.6V) | Supports reliable operation in high-pin-count, simultaneously-switching-output (SSO) configurations |
| Flow-Through Pinout | Minimizes layer count and via usage in dense backplane routing; simplifies layout verification |
| Hysteresis on All Inputs | Provides 100mV noise margin against crosstalk and rail noise on enable and data lines |
Applications
| Industrial Backplane Interface | Telecom Line Card Buffering |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT162244CPAG | Same ±24mA drive but SSOP-48 package (300 mil); higher ground bounce (0.8V typ.) | Larger footprint limits use in ultra-dense telecom modules | Select when legacy SSOP footprint compatibility is required and board space allows |
| 74LVC162244APAG | 3.3V-only operation; lower drive (±24mA @ 3.3V), no built-in edge control | Requires external series resistors for EMI control; incompatible with 5V systems | Choose only for new 3.3V designs where voltage scaling justifies added component count |
Compared with SN74FCT162244CPAG, PI74FCT162244ATV offers superior noise control in tight layouts due to TVSOP's lower inductance and tighter ground bounce spec; versus 74LVC162244APAG, it delivers full 5V interoperability and integrated edge-rate management without design overhead.

FAQ
What is the maximum clock frequency supported by PI74FCT162244ATV?
PI74FCT162244ATV is not a clocked device-it has no internal clock or register function. Its propagation delay (1.5–6.5ns) supports reliable operation in parallel bus systems running up to 100MHz, assuming proper trace length matching and load capacitance ≤50pF per output.
Does PI74FCT162244ATV support live insertion or hot-swap?
No-only the PI74FCT16244T variant includes Power-Off Disable for live insertion. PI74FCT162244ATV lacks this feature; its outputs go high-impedance only when XOE is asserted, and it requires VCC to be present for functional 3-state control.
Can PI74FCT162244ATV drive unterminated 50Ω transmission lines?
Yes-its ±24mA drive strength and built-in edge-rate control allow direct connection to 50Ω lines without external series resistors in most cases. Measured ground bounce remains below 0.6V, making it suitable for point-to-point or short-drop multidrop configurations up to 15cm.
Is there a pin-compatible 3.3V version of PI74FCT162244ATV?
No-PI74FCT162244ATV is strictly 5V-operated. The closest functional equivalents (e.g., 74LVC162244A) operate at 3.3V but require different VCC, lack hysteresis, and do not replicate the edge-rate control or ground bounce performance of the FCT family.
