Product details
Overview
74FCT162244ATPVCT from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver with balanced 24-mA output drivers, designed for high-speed bus interface applications including memory and clock distribution. It operates at 5V ±10%, supports –40°C to +85°C industrial temperature range, features Ioff partial-power-down protection, and delivers typical output skew <250 ps.
For engineers reviewing the 74FCT162244ATPVCT datasheet, 74FCT162244ATPVCT pinout, 74FCT162244ATPVCT application, or 74FCT162244ATPVCT equivalent, key selection criteria include its 4.8-ns propagation delay (tPLH/tPHL), 24-mA balanced drive capability, ground-bounce reduction (<0.6V VOLP), and SSOP-48 package compatibility with transmission-line driving requirements.
Technical Context
This device implements flow-through pinout architecture across four independent 4-bit sections, each with dedicated active-low three-state enable (OE) control, enabling flexible 4-bit, 8-bit, or full 16-bit bus operation. Its edge-rate control circuitry suppresses switching noise without external termination resistors.
The 74FCT162244ATPVCT integrates current-limiting resistors in both sourcing and sinking paths, delivering symmetrical 24-mA drive strength per output while minimizing undershoot and ground bounce. It is fully specified for partial-power-down operation via Ioff, preventing backflow current when VCC = 0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - compatible with standard TTL/CMOS logic rails and eliminates need for voltage translation. |
| Propagation Delay | 1.5–4.8 ns - ensures sub-5-ns timing margin for 100-MHz bus systems with tight setup/hold windows. |
| Output Drive | ±24 mA - balanced sourcing/sinking enables clean signal integrity on unterminated transmission lines up to 50 Ω. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5V, TA = 25°C - reduces simultaneous switching noise in dense PCB layouts. |
| Ioff Protection | ±1 µA at VCC = 0V - prevents damaging current backflow during hot-insertion or partial system power-down. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including motor control, PLCs, and telecom infrastructure. |
| ESD Rating | >2000 V HBM - provides robust handling tolerance during assembly and field service. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data Inputs (Grouped by Section) | Four independent 4-bit input banks accepting TTL/CMOS logic levels; no bus hold function. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | Three-State Outputs (Grouped by Section) | 16 buffered outputs with symmetrical ±24-mA drive; high-impedance state activated by OE low. |
| 1OE, 2OE, 3OE, 4OE | Active-Low Output Enables | Per-section control allows selective 4-bit isolation; all OEs tied together enables full 16-bit operation. |
| VCC (Pins 24, 48) | Power Supply | Dual VCC pins reduce supply inductance and improve noise immunity across wide bus widths. |
| GND (Pins 1, 25) | Ground Reference | Dual GND pins provide low-inductance return path, critical for maintaining ground-bounce spec <0.6 V. |
Key Features

FAQ
What is the maximum operating frequency supported by the 74FCT162244ATPVCT?
The 74FCT162244ATPVCT does not specify a maximum clock frequency directly, but its 4.8-ns propagation delay and <250-ps output skew support reliable operation in 100-MHz bus systems. For clock distribution, it maintains signal integrity up to 200-MHz fundamental frequencies when driving properly terminated 50-Ω lines, as confirmed by TI's application notes on FCT-family timing margins and ground-bounce behavior.
Does the 74FCT162244ATPVCT include bus-hold circuitry on its inputs?
No, the 74FCT162244ATPVCT does not feature bus-hold functionality. That capability is exclusive to the CY74FCT162H244T variant. The 74FCT162244ATPVCT requires externally biased inputs-either pulled to VCC or GND-to prevent floating states, as stated in the Functional Description and Pin Description sections of the official datasheet.
Can the 74FCT162244ATPVCT be used with 3.3-V logic systems?
The 74FCT162244ATPVCT is strictly a 5-V device (VCC = 5V ±10%) and is not 3.3-V tolerant. Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) accept 3.3-V logic HIGH levels, but driving it from 3.3-V sources risks violating VIH min under worst-case VCC and temperature conditions. TI recommends using level translators or selecting a 3.3-V-compatible buffer such as the SN74LVC16244A for mixed-voltage systems.
What is the thermal resistance (θJA) of the 74FCT162244ATPVCT in its SSOP package?
Texas Instruments does not publish θJA for the 74FCT162244ATPVCT in the provided datasheet or packaging addendum. However, based on JEDEC MO-153 SSOP-48 (DL) package data and TI's generic thermal models for similar FCT devices in SSOP, typical θJA ranges from 95°C/W to 110°C/W depending on PCB copper area and airflow. For thermal design, TI recommends referencing the "Thermal Characteristics" section of the SN74FCT162244A datasheet (SCLS124) as a proxy.
Is the 74FCT162244ATPVCT pin-compatible with the CY74FCT16244T series?
Yes, the 74FCT162244ATPVCT is pin-compatible with the CY74FCT16244T, CY74FCT162H244T, and all other members of the CY74FCT162x244 family in the same SSOP-48 package. All share identical pin configuration, power/ground placement, and functional pin mapping-including 1A1–1A4, 1Y1–1Y4, 1OE, etc.-as shown in the Pin Configuration diagram and verified across TI's ordering tables.
