Product details
Overview
PI74FCT162244ATAE from Pericom Semiconductor is a 16-bit non-inverting 3-state buffer/line driver with ±24mA balanced 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 external termination in most interfaces. Operates at 5V ±10% over –40°C to +85°C.
For engineers reviewing the PI74FCT162244ATAE datasheet, PI74FCT162244ATAE pinout, PI74FCT162244ATAE application, or PI74FCT162244ATAE equivalent, key selection criteria include output drive symmetry, low ground bounce performance, flow-through pinout for PCB layout efficiency, and compatibility with TTL-level inputs and 5V systems.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low 3-state enable (xOE). Its flow-through pinout-inputs on one side, outputs on the opposite-minimizes trace crossovers in dense backplane layouts. All inputs include hysteresis for noise immunity on slow-rising signals.
The output stage integrates on-die current-limiting resistors to shape rise/fall times, directly lowering simultaneous switching noise (SSN), VOLP, and undershoot without requiring external series termination. Power-off disable is not implemented-unlike the PI74FCT16244T variant-making it optimized for static 5V bus driving rather than hot-swap backplanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS 5V logic rails |
| Output Drive Current | ±24 mA - symmetric sourcing/sinking enables matched signal integrity on bidirectional buses |
| Propagation Delay | 1.5–6.5 ns (CL = 50 pF) - supports >150 MHz data rates in short traces |
| Ground Bounce (VOLP) | <0.6 V typical - reduces false triggering in adjacent logic due to reduced SSN |
| Input Hysteresis | 100 mV - improves noise margin on unterminated or long stubs |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and telecom infrastructure |
| Input Capacitance | 4.5–7.5 pF - low loading preserves timing margins in fan-out-heavy designs |
Pinout & Package
PI74FCT162244ATAE uses a 48-pin 240-mil wide plastic TSSOP (Package Code A), Pb-free and RoHS-compliant per ordering suffix "E".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low 3-state enable inputs | Independent control of each 4-bit buffer group; enables quad-nibble mode operation |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | Non-inverting input terminals | 16 total inputs arranged for byte- and nibble-aligned addressing |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 | 3-state buffered outputs | Flow-through layout places outputs opposite corresponding inputs for minimal layer routing |
| VCC (Pins 7, 16, 25, 34, 43) | Power supply | Five distributed VCC pins reduce IR drop and improve PSRR across wide bus |
| GND (Pins 1, 10, 19, 28, 37) | Ground reference | Five GND pins provide low-inductance return paths, critical for low-VOLP performance |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| SN74FCT162244CTPV | Same core logic but in 48-pin SSOP (V package); higher thermal resistance (θJA = 90°C/W vs. 75°C/W) | Preferred where board space allows wider body and manual rework is required | Select when SSOP footprint matches existing stencil or when thermal derating above 70°C ambient is acceptable |
| 74LVC162244APAG | 3.3V-only operation; lower drive (±24mA @ 3.3V, not 5V); no integrated current limiting | Requires external series termination and level-shifting for 5V bus interfacing | Choose only for new 3.3V-only designs with tight power budgets and no legacy 5V interface requirements |
Compared with SN74FCT162244CTPV and 74LVC162244APAG, PI74FCT162244ATAE uniquely delivers 5V-compatible ±24mA drive with built-in edge-rate control in a thermally optimized TSSOP package-enabling drop-in replacement in legacy industrial backplane designs without layout or BOM revision.

FAQ
Is PI74FCT162244ATAE pin-compatible with PI74FCT16244T?
No. While both are 48-pin TSSOP 16-bit buffers, PI74FCT162244T has balanced ±24mA outputs and no power-off disable, whereas PI74FCT16244T provides asymmetric –32mA/+64mA drive and supports live insertion via power-off disable. Pin functions differ in enable logic and internal termination structure.
Does PI74FCT162244ATAE support hot-swap or live-insertion?
No. Unlike the PI74FCT16244T variant, PI74FCT162244ATAE lacks power-off disable functionality. Its outputs do not enter high-impedance state when VCC = 0V, making it unsuitable for hot-plug backplane applications.
What is the maximum capacitive load this device can drive reliably?
Based on characterization at CL = 50 pF and RL = 500 Ω, the device maintains specified tPLH/tPHL and VOLP < 0.6 V up to 100 pF per output. For loads exceeding 75 pF, verify timing margins using the provided propagation delay vs. load curves in the original datasheet.
Can PI74FCT162244ATAE be used with 3.3V logic inputs?
Yes. Its VIH(min) = 2.0 V and VIL(max) = 0.8 V ensure full compatibility with 3.3V CMOS and TTL outputs. However, VCC must remain at 5.0 V ±10% to guarantee ±24mA drive strength and timing specifications.
