Product details
Overview
74FCT16244TPVCG4 from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver designed for high-speed memory and bus interface applications. It delivers 64 mA sink and 32 mA source drive capability, supports Ioff partial-power-down protection, operates at VCC = 5V ±10%, and features typical output skew <250 ps. It is used in industrial backplane driving where low ground bounce (<1.0V) and noise-immune edge-rate control are critical.
For engineers reviewing the 74FCT16244TPVCG4 datasheet, 74FCT16244TPVCG4 pinout, 74FCT16244TPVCG4 application, or 74FCT16244TPVCG4 equivalent, key selection criteria include its 48-pin SSOP package, 6.5 ns max propagation delay, industrial temperature range (–40°C to +85°C), and compatibility with TTL-level inputs and 5V CMOS outputs in high-capacitance load environments.
Technical Context
This device implements four independent 4-bit groups of non-inverting buffers, each with dedicated active-low three-state enable (OE) controls. Its flow-through pinout simplifies PCB layout for parallel bus routing, and Ioff circuitry ensures no damaging current flows when VCC = 0V.
The 74FCT16244TPVCG4 uses FCT logic family architecture optimized for speed-power trade-off: it achieves 6.5 ns max tPLH/tPHL while maintaining quiescent ICC ≤ 500 µA and dynamic ICCD ≤ 100 µA/MHz, with edge-rate limiting to suppress simultaneous switching noise.
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 | 6.5 ns max (tPLH/tPHL) - enables reliable operation in 150+ MHz bus systems with timing margin |
| Output Drive | 64 mA sink / 32 mA source - sufficient to drive 50-Ω transmission lines or high-capacitance backplanes directly |
| Ground Bounce | VOLP <1.0V at VCC=5V, TA=25°C - reduces signal integrity risk in dense multi-driver layouts |
| Ioff Support | Active at VCC = 0V - prevents backflow current during hot-swap or partial power-down sequences |
| ESD Rating | >2000V HBM - meets industrial handling robustness requirements without external protection |
| Operating Temp | –40°C to +85°C - qualified for extended industrial environments including factory automation and telecom infrastructure |
Pinout & Package
74FCT16244TPVCG4 is housed in a 48-pin SSOP (Shrink Small Outline Package), 300-mil body width, 0.025-inch pitch, 1.2 mm max height, JEDEC MO-153 compliant. Pin 1 marked by notch or dot; pin 1 ID area located at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data Inputs (Grouped) | Four independent 4-bit input banks accepting TTL/CMOS logic levels; no internal bus hold |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | Three-State Outputs | Non-inverting buffered outputs; high-impedance when corresponding OE is HIGH |
| 1OE, 2OE, 3OE, 4OE | Active-Low Output Enables | Per-group control: LOW enables 4 outputs; HIGH places them in high-Z state |
| VCC (Pins 24, 48) | Power Supply | Dual VCC pins reduce supply inductance and improve noise immunity across wide bus |
| GND (Pins 1, 12, 25, 36) | Ground | Four distributed GND pins minimize ground bounce and ensure stable reference for all 16 drivers |
Key Features
| Feature | Design Value |
|---|---|
| Ioff Partial-Power-Down Protection | Disables outputs and blocks reverse current flow when VCC = 0V - essential for hot-plug and mixed-voltage system interoperability |
| Edge-Rate Controlled Outputs | Internally limited slew rate reduces EMI and crosstalk in high-density routing - eliminates need for external series termination in many cases |
| Flow-Through Pinout | Input and output pins aligned on opposite sides of package - enables straight trace routing and minimizes layer transitions on 2-layer PCBs |
| Low Ground Bounce (VOLP) | <1.0V at 64 mA sink - maintains signal integrity under heavy capacitive loading without external decoupling overdesign |
| Industrial Temperature Range | –40°C to +85°C operation - validated across full range for use in uncontrolled ambient environments like base station cabinets or motor drives |
Applications
| Memory Interface Driver | Clock Distribution Buffer |
|---|---|
Use Scenario: Driving address/data buses between FPGA and SRAM/Flash in industrial controllers. IC Role / Device Role / Timing Role: Non-inverting 16-bit buffer providing level-shifting, fanout expansion, and bus isolation. Use Value: 64 mA sink capability ensures clean signal edges into 30+ pF per line loads; 6.5 ns delay allows tight setup/hold timing closure. | Use Scenario: Distributing a single clock signal to multiple synchronous peripherals in PLC modules.

IC Role / Device Role / Timing Role: High-current line driver enabling direct connection to unterminated backplane traces. Use Value: 64 mA sink strength drives 50-Ω loads without external series resistors; edge-rate control prevents overshoot beyond 5V rail. | Use Scenario: Isolating ISA or VME bus segments in retrofitted instrumentation systems. IC Role / Device Role / Timing Role: Three-state bidirectional buffer enabling controlled bus segment enable/disable. Use Value: Four independent OE controls allow selective activation of 4-bit sub-buses - simplifies arbitration logic and reduces contention risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT162244TPVC | 24 mA balanced drive (sink/source), lower ground bounce (<0.6V), no Ioff support | Better suited for transmission-line driving with matched impedance; less tolerant of partial power-down scenarios | Select when driving controlled-impedance lines and system power sequencing does not require Ioff |
| 74FCT162H244TPVC | 24 mA drive with bus-hold inputs; eliminates need for external pull-up/down resistors | Preferred for floating-input environments (e.g., unpopulated slots); higher input leakage (±100 µA) vs. standard FCT | Select when input nodes may float and board space for pull resistors is constrained |
Compared with CY74FCT162244TPVC and 74FCT162H244TPVC, the 74FCT16244TPVCG4 provides highest drive strength and Ioff protection but lacks bus-hold and has higher ground bounce - making it optimal for high-current, hot-swap-capable backplane interfaces rather than point-to-point transmission lines or floating-input systems.

FAQ
What is the maximum operating frequency supported by the 74FCT16244TPVCG4?
The 74FCT16244TPVCG4 does not specify a maximum operating frequency directly, but its 6.5 ns maximum propagation delay (tPLH/tPHL) and 5.6 ns maximum output disable time (tPLZ) support reliable operation in bus systems up to approximately 150 MHz, assuming adequate setup/hold margins and proper PCB layout. Actual usable frequency depends on load capacitance, trace length, and termination strategy.
Does the 74FCT16244TPVCG4 support hot-swap or partial-power-down operation?
Yes, the 74FCT16244TPVCG4 includes Ioff circuitry that disables outputs and blocks reverse current flow when VCC = 0V, enabling safe hot-swap and partial-power-down operation. This feature is explicitly verified in the datasheet and allows the 74FCT16244TPVCG4 to be powered down independently while other devices on the same bus remain active.
What package type and dimensions does the 74FCT16244TPVCG4 use?
The 74FCT16244TPVCG4 uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 0.025-inch lead pitch. Its mechanical outline conforms to JEDEC MO-153, with overall dimensions of 12.6 mm × 6.2 mm × 1.2 mm max height. Pin 1 is identified by a notch or dot in the top-left corner.
Can the 74FCT16244TPVCG4 drive 50-Ω transmission lines directly?
Yes, the 74FCT16244TPVCG4 can drive 50-Ω transmission lines directly due to its 64 mA sink and 32 mA source capability, which approximates a 78 Ω (5V/64 mA) effective output impedance. While not a true 50 Ω driver, its strength and edge-rate control allow clean signaling into unterminated 50 Ω lines up to ~10 cm; longer traces benefit from series termination near the driver.
Is the 74FCT16244TPVCG4 pin-compatible with other members of the CY74FCT162xx4T family?
No, the 74FCT16244TPVCG4 is not pin-compatible with CY74FCT162244TPVC or CY74FCT162H244TPVC despite identical 48-pin SSOP packaging and shared pinout structure - differences in internal circuitry (e.g., bus-hold on inputs for H-version, current-limiting resistors for 2244T) mean functional behavior differs per pin group, and substitution requires validation of timing, drive strength, and power-down behavior in the target application.
