Product details
Overview
PI74FCT162244ATVE from Pericom Semiconductor is a 16-bit non-inverting buffer/line driver with balanced ±24mA output drive, 3-state control per nibble/byte/word, and integrated current-limiting resistors for controlled edge rates. It operates at 5V ±10%, delivers <0.6V typical ground bounce, and targets high-capacitance backplane and low-impedance bus interface applications in industrial control and telecom line cards.
For engineers reviewing the PI74FCT162244ATVE datasheet, PI74FCT162244ATVE pinout, PI74FCT162244ATVE application, or PI74FCT162244ATVE equivalent, key selection criteria include output drive symmetry, ground bounce performance, flow-through pin layout, and compatibility with live-insertion backplane architectures requiring controlled slew and termination-free operation.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low 3-state enable (xOE), enabling flexible partitioning into quad-nibble, dual-byte, or full 16-bit modes. All inputs feature hysteresis for noise immunity on slow-rising signals.
Output drivers integrate on-die current-limiting resistors to reduce dI/dt-induced ground bounce and undershoot-eliminating external series termination in most PCB trace interfaces. The design supports live insertion via power-off disable behavior when VCC = 0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5.0V ±10% - Operates within standard TTL-compatible logic rail; supports legacy 5V system integration. |
| Output Drive | ±24mA - Balanced sourcing/sinking ensures symmetrical signal integrity on bidirectional buses. |
| Ground Bounce | <0.6V typical at VCC = 5V, TA = 25°C - Enables stable multi-bit switching without board-level decoupling overdesign. |
| Propagation Delay | 1.5–6.5ns (CL = 50pF) - Supports >150MHz data rates in point-to-point or lightly loaded stubbed topologies. |
| Input Hysteresis | 100mV - Rejects noise up to 100mV on input transitions, critical for noisy industrial environments. |
| Quiescent Current | 0.1–500μA - Ultra-low static power enables use in always-on monitoring subsystems. |
| Operating Temperature | –40°C to +85°C - Qualified for extended industrial temperature range deployment. |
Pinout & Package
Package: 48-pin 300-mil wide plastic SSOP (Package Code V), Pb-free & Green compliant (E suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low 3-state enable inputs | Independent control per 4-bit group enables dynamic bus segmentation and power-gating of unused sections. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | Non-inverting input terminals | Flow-through layout aligns inputs and outputs on opposite sides for minimal trace crossovers in dense backplane routing. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 | 3-state buffered output terminals | Current-limited outputs suppress simultaneous switching noise without external resistors or layout constraints. |
| VCC (Pins 7, 15, 23, 31, 39) | Power supply | Five distributed VCC pins reduce IR drop and improve high-frequency decoupling across the 48-pin array. |
| GND (Pins 1, 9, 17, 25, 33, 41) | Ground reference | Six GND pins provide low-inductance return paths, critical for maintaining <0.6V ground bounce spec. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA outputs | Enables matched rise/fall times on transmission lines, reducing EMI and jitter in synchronous bus interfaces. |
| Integrated slew rate control | On-die current-limiting resistors eliminate need for external series termination in >90% of 50Ω–75Ω trace applications. |
| Flow-through pinout | Input and output pins arranged on opposing edges simplify layer stacking and minimize vias in 4-layer PCB layouts. |
| Hysteresis on all inputs | 100mV threshold margin prevents chatter on slow-slew or noisy control signals in factory automation I/O modules. |
| Power-off disable | Outputs enter high-impedance state when VCC = 0V, enabling hot-swap capability in modular telecom chassis designs. |

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 |
|---|---|---|---|
| SN74FCT162244CTV | Same pinout and function but rated for commercial temperature only (0°C to +70°C); no hysteresis on inputs. | Lacks industrial temp range and noise immunity-unsuitable for factory-floor PLC modules. | Select only for cost-sensitive, ambient-controlled lab or office equipment. |
| 74LVC162244APAG | 3.3V-only operation; 24mA drive asymmetry (IOH = –24mA, IOL = 24mA); no built-in slew control. | Requires external termination and level-shifting for 5V systems; higher ground bounce risk. | Use only in new 3.3V designs where voltage translation and layout simplicity are secondary to footprint reduction. |

FAQ
Is PI74FCT162244ATVE pin-compatible with PI74FCT162244CTV?
Yes-both share identical 48-pin SSOP (V) package, pin assignment, and logic function. The 'A' speed grade (PI74FCT162244ATVE) guarantees tighter propagation delay (max 4.8ns vs. 4.1ns for 'C') and same ±24mA drive, making it a direct performance upgrade with no layout change required.
Does PI74FCT162244ATVE require external termination resistors?
No-its integrated current-limiting resistors control output edge rates, reducing ground bounce and eliminating external series termination in most 50Ω–75Ω PCB trace applications. Only exceptionally long (>20cm) or heavily branched stubs may need supplemental matching.
What is the maximum capacitive load this device can drive reliably?
It drives up to 100pF per output while maintaining <0.6V ground bounce and ≤6.5ns propagation delay. At 50pF load (standard test condition), tPLH/tPHL remains within 1.5–6.5ns across –40°C to +85°C, supporting reliable operation in dense backplane routing.
Can PI74FCT162244ATVE be used in mixed-voltage systems with 3.3V controllers?
Yes-as a 5V buffer, it accepts 3.3V-tolerant inputs (VIH = 2.0V min, VIL = 0.8V max). When driven by 3.3V logic, its 5V outputs provide sufficient noise margin for downstream 5V receivers, but level-shifting is required if feeding 3.3V-only inputs.
