Product details
Overview
PI74FCT162244ATA from Pericom Semiconductor is a 16-bit non-inverting buffer/line driver with ±24mA balanced output drive, designed for high-capacitance backplane and bus interface applications. It features three-state control for quad-nibble or dual-byte operation, current-limiting output resistors to suppress ground bounce (<0.6V typical), and operates at 5V ±10% over –40°C to +85°C.
For engineers reviewing the PI74FCT162244ATA datasheet, PI74FCT162244ATA pinout, PI74FCT162244ATA application, or PI74FCT162244ATA equivalent, key selection criteria include output drive symmetry, low-ground-bounce performance, flow-through pin layout for PCB routing, and compatibility with TTL-level inputs and 5V systems requiring controlled edge rates without external termination.
Technical Context
This device implements a 16-bit, non-inverting, three-state buffer architecture with independent 4-bit group enable controls (1OE–4OE). Each output stage integrates on-die current-limiting resistors to shape rise/fall times and reduce simultaneous switching noise.
It supports mixed-mode operation: all 16 bits can be enabled together, or partitioned into four 4-bit nibbles via discrete OE pins. Input hysteresis (100mV) ensures noise immunity on slow-rising signals, and power-off disable behavior is not implemented-unlike the PI74FCT16244T variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5.0V ±10% - compatible with standard 5V TTL/CMOS logic rails and industrial power supplies |
| Output Drive | ±24mA - balanced sourcing/sinking enables matched signal integrity on bidirectional buses |
| Ground Bounce | <0.6V typical at VCC = 5V - reduced system-level noise without external termination resistors |
| Propagation Delay | 1.5–6.5ns (CL = 50pF) - supports >150MHz data rates in point-to-point or lightly loaded backplane links |
| Input Hysteresis | 100mV - improves noise margin for noisy or slow-edge control signals in industrial environments |
| Operating Temperature | –40°C to +85°C - qualified for extended-temperature industrial and telecom infrastructure use |
| Input Capacitance | 4.5–7.5pF - low loading preserves signal integrity across long traces or fanout to multiple loads |
Pinout & Package
Package: 48-pin, 240-mil wide plastic TSSOP (Package Code A), Pb-free & Green compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 4-bit group output enable | Enables/disables four independent 4-bit output sections; allows flexible bus segmentation |
| 1A0–4A3 | Non-inverting input (16 total) | Direct logic pass-through with hysteresis; accepts TTL-compatible 0.8V/2.0V thresholds |
| 1Y0–4Y3 | Three-state buffered output (16 total) | ±24mA drive with internal slew control; enters high-Z when corresponding OE is HIGH |
| VCC, GND | Power supply and reference | Dual VCC/GND pairs per side minimize supply inductance and improve noise rejection |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA outputs | Equal sourcing/sinking capability maintains signal symmetry on stubbed or unterminated lines |
| Integrated output current limiting | Eliminates need for external series resistors while controlling edge rate and reducing EMI |
| Flow-through pinout | Inputs on one side, outputs on opposite side - simplifies layer routing and reduces crosstalk |
| 100mV input hysteresis | Rejects sub-100mV noise transients on control or data lines in electrically noisy enclosures |
| Low ground bounce (<0.6V) | Minimizes logic errors caused by simultaneous output switching in dense PCB layouts |
Applications

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 56-pin SSOP package; higher ICCD (100μA/MHz vs. 60μA/MHz) | Larger footprint; less suitable for space-constrained backplane cards | Select when board layout requires wider pitch or legacy SSOP tooling compatibility |
| 74LVC162244APAG | 3.3V-only operation; lower drive (±24mA @ 3.3V), no built-in hysteresis | Not interoperable with 5V systems; requires level translation for mixed-voltage designs | Select only for new 3.3V-only designs where lower static power and smaller die size are prioritized |
Compared with SN74FCT162244CPAG and 74LVC162244APAG, the PI74FCT162244ATA offers optimal trade-offs for 5V industrial backplanes: smallest TSSOP footprint, lowest ground bounce, and integrated hysteresis-without sacrificing drive strength or temperature range.

FAQ
Is PI74FCT162244ATA pin-compatible with PI74FCT16244ATA?
No. While both are 48-pin TSSOP 16-bit buffers, PI74FCT16244ATA has asymmetric drive (–32mA/64mA) and power-off disable, whereas PI74FCT162244ATA uses symmetric ±24mA outputs without power-off disable. Pin functions differ in OE assignment and internal biasing-direct substitution will cause functional failure.
Can PI74FCT162244ATA drive 100Ω transmission lines directly?
No. Its ±24mA outputs are optimized for capacitive loads up to ~100pF and stubbed backplane traces-not continuous 100Ω differential or single-ended transmission lines. For such applications, use a dedicated line driver IC with proper impedance matching and differential signaling support.
What is the maximum recommended capacitive load per output?
The datasheet characterizes performance up to 50pF load (for tPLH/tPHL specs), but practical design limits are ~100pF per output. Beyond that, propagation delay increases and ground bounce may exceed 0.6V; derating is required for reliable operation at full speed with heavy fanout.
Does PI74FCT162244ATA support hot-swap insertion?
No. Unlike the PI74FCT16244T variant, this part lacks power-off disable functionality. Applying VCC after signal inputs may cause latch-up or excessive current draw. Board-level hot-swap requires external sequencing or protection circuitry.
