Product details
Overview
CY74FCT163244CPACT from Texas Instruments is a 16-bit non-inverting 3-state buffer/line driver with balanced 24 mA output drive, designed for memory and clock bus interface applications in industrial systems operating from 2.7V to 3.6V. It features 4.1 ns propagation delay (tPLH/tPHL), 5V-tolerant inputs/outputs, and power-off high-impedance outputs enabling live insertion.
For engineers reviewing the CY74FCT163244CPACT datasheet, CY74FCT163244CPACT pinout, CY74FCT163244CPACT application, or CY74FCT163244CPACT equivalent, key selection criteria include its TSSOP-48 package, industrial temperature range (–40°C to +85°C), bus-hold-free input architecture, and compatibility with 3.3V LVTTL/LVCMOS systems requiring low-noise, high-speed buffering with controlled edge rates.
Technical Context
This device implements four independent 4-bit groups of non-inverting buffers, each with dedicated active-low 3-state enable (OE) control, supporting flexible 4-bit, 8-bit, or full 16-bit bus operation. Its flow-through pinout minimizes trace routing complexity on dense PCBs.
It uses FCT-C logic family architecture with current-limiting resistors integrated into 24 mA balanced output drivers, delivering consistent VOH/VOL across load conditions while meeting JEDEC JESD78 latch-up immunity (>500 mA) and >2000V HBM ESD robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - Supports standard 3.3 V supply rails with ±0.3 V tolerance margin. |
| Propagation Delay | 4.1 ns max at VCC = 3.0–3.6 V - Enables reliable operation in high-speed memory and clock distribution paths up to ~200 MHz. |
| Output Drive | ±24 mA balanced - Ensures stable signal integrity driving unterminated stubs or multiple CMOS loads without external termination. |
| Input Voltage | 5 V tolerant - Allows direct interfacing with legacy 5 V TTL/CMOS logic without level-shifting circuitry. |
| Operating Temp | –40°C to +85°C - Qualified for industrial environments including factory automation and telecom infrastructure. |
| Output Skew | < 250 ps typical - Minimizes timing mismatch across 16-bit data paths critical for synchronous bus integrity. |
| Power-Off Disable | IOFF ≤ ±100 µA at VCC = 0 V - Prevents back-driving and enables hot-plug capability in modular backplane systems. |
Pinout & Package
Package: 48-pin TSSOP (Z48), 240-mil body width, 0.25 mm pitch, JEDEC MO-153 compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data Inputs (Group 1–4) | Four independent 4-bit input buses accepting 5 V tolerant logic levels; no bus hold function. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-State Outputs (Group 1–4) | Non-inverting buffered outputs with 24 mA drive; enter high-Z when corresponding OE is HIGH. |
| 1OE, 2OE, 3OE, 4OE | Active-Low Output Enables | Independent per-group control; all outputs go high-impedance when asserted LOW (logic 0). |
| VCC (Pins 24, 48) | Power Supply | Dual VCC pins reduce supply noise coupling and improve PSRR across wide bandwidth. |
| GND (Pins 1, 25) | Ground Reference | Dual ground pins provide low-inductance return path for switching currents, minimizing ground bounce (Volp). |
Key Features
| Feature | Design Value |
|---|---|
| Edge-rate control circuitry | Reduces simultaneous switching noise (SSN) and EMI emissions without external RC networks. |
| Flow-through pinout | Minimizes layer count and trace length in high-density PCB layouts, lowering parasitic inductance/capacitance. |
| 24 mA balanced output drive | Delivers symmetrical rise/fall times under load, preserving signal duty cycle integrity in clock distribution. |
| JEDEC JESD78 latch-up immunity | Exceeds 500 mA stress current - ensures robust operation in noisy industrial power environments. |
| Typical output skew < 250 ps | Enables tight timing margins in parallel data buses where inter-bit skew directly impacts setup/hold windows. |
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 |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (24 mA sink / 24 mA source), same 48-pin TSSOP, but only 3.6 V max VCC and no 5 V tolerance. | Requires external level shifters for 5 V interface; unsuitable for mixed-voltage backplanes. | Select when cost-sensitive designs operate strictly within 3.3 V domains and do not require 5 V tolerance. |
| 74FCT16244CTPVCT | Same FCT family, SSOP-48 package (O48), 4.8 ns propagation delay, identical electrical specs except slower timing. | Compatible pinout but larger footprint; suitable where board space permits and 4.8 ns delay is acceptable. | Select when SSOP packaging is preferred for thermal or mechanical reasons, and minor timing degradation is acceptable. |
Compared with SN74LVC16244ADGGR and 74FCT16244CTPVCT, CY74FCT163244CPACT uniquely combines 5 V tolerance, 4.1 ns speed, and TSSOP-48 packaging-making it the only option for high-speed, mixed-voltage industrial bus buffering without layout or voltage rail changes.

FAQ
What is the maximum operating frequency supported by CY74FCT163244CPACT?
CY74FCT163244CPACT does not specify a maximum clock frequency in its datasheet, as it is a combinational buffer-not a clocked device. However, its 4.1 ns propagation delay and <250 ps output skew support reliable operation in 16-bit parallel buses running at effective data rates up to 200+ MHz, assuming proper PCB layout and load conditions. The actual usable frequency depends on system-level timing margins, trace lengths, and capacitive loading.
Does CY74FCT163244CPACT include bus-hold circuitry on its inputs?
No, CY74FCT163244CPACT does not include bus-hold functionality. That feature is exclusive to the CY74FCT163H244 variant. CY74FCT163244CPACT requires externally biased inputs (e.g., pull-up/down resistors) when driven by high-impedance sources to prevent floating states, unlike its H-series counterpart which retains last valid logic state automatically.
What package type and dimensions does CY74FCT163244CPACT use?
CY74FCT163244CPACT uses a 48-pin TSSOP (Thin Shrunk Small Outline Package), designated Z48 per TI's ordering nomenclature. Its body measures 12.5 mm × 6.1 mm with 0.25 mm lead pitch, conforms to JEDEC MO-153, and has MSL Level 3 moisture sensitivity. This compact, surface-mount package supports high-density industrial PCB layouts while maintaining thermal and mechanical reliability.
Can CY74FCT163244CPACT be used with a 5 V supply?
No, CY74FCT163244CPACT is rated for VCC = 2.7 V to 3.6 V only. While its inputs and outputs are 5 V tolerant-meaning they safely accept and drive 5 V signals-the internal core logic requires a 3.3 V nominal supply. Applying 5 V to VCC will exceed absolute maximum ratings and cause permanent damage. Always power CY74FCT163244CPACT from a regulated 3.3 V rail.
How does the power-off disable feature work in CY74FCT163244CPACT?
The power-off disable feature in CY74FCT163244CPACT ensures that all outputs enter a high-impedance state when VCC = 0 V, with leakage current limited to ±100 µA per pin. This prevents back-driving of powered downstream circuits during hot-swap events or partial system power-down-critical for modular backplane and rack-mounted industrial systems. The function operates independently of OE pin state.
