Product details

Overview

74FCT16244CTPVCTG4 from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver optimized for high-speed bus interface applications. It delivers 64 mA sink and 32 mA source drive capability, supports partial-power-down via I_off, operates at 5V ±10%, and features typical output skew <250 ps and ground bounce <1.0 V - enabling robust driving of high-capacitance loads and low-impedance backplanes.

For engineers reviewing the 74FCT16244CTPVCTG4 datasheet, 74FCT16244CTPVCTG4 pinout, 74FCT16244CTPVCTG4 application, or 74FCT16244CTPVCTG4 equivalent, key selection criteria include its 4.1 ns max propagation delay (t_PLH/t_PHL), industrial temperature range (–40°C to +85°C), SSOP-48 package with 300-mil body, and I_off-enabled power-down protection in mixed-voltage systems.

Technical Context

This device implements four independent 4-bit groups of non-inverting buffers, each with dedicated active-low three-state enable (OE) inputs, allowing flexible 4-bit, 8-bit, or full 16-bit bus control. Its flow-through pinout minimizes trace routing complexity on dense PCBs.

The 74FCT16244CTPVCTG4 uses FCT logic family architecture with edge-rate control circuitry to suppress switching noise and reduce EMI. It is fully specified for partial-power-down operation: when V_CC = 0 V, I_off limits current backflow to ±1 µA per I/O, protecting powered-down sections of the system.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Supply	5 V ±10% - compatible with standard TTL/CMOS logic rails; no level-shifting required in 5-V systems.
Propagation Delay	Max 4.1 ns (t_PLH/t_PHL) - enables reliable operation in high-speed memory and clock distribution up to ~200 MHz.
Output Drive	64 mA sink / 32 mA source - sufficient to drive 50-Ω transmission lines or 100-pF capacitive loads without external termination.
Output Skew	<250 ps typical - ensures tight timing alignment across all 16 outputs, critical for synchronous bus integrity.
I_off Current	±1 µA at V_CC = 0 V - prevents damaging back-current during hot-insertion or partial system power-down.
ESD Rating	>2000 V HBM - provides robust handling margin in manufacturing and field environments.
Operating Temp	–40°C to +85°C - validated for industrial-grade reliability without derating.

Pinout & Package

74FCT16244CTPVCTG4 is housed in a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 25-mil lead pitch. The package is RoHS-compliant and designed for surface-mount reflow assembly.

Pin/Terminal	Circuit Role	Design Meaning
1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4	Data Inputs (Grouped)	Four banks of 4-bit inputs; each bank drives corresponding Y outputs when OE is active.
1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4	Three-State Outputs	Non-inverting buffered outputs; high-impedance when respective OE is HIGH.
1OE, 2OE, 3OE, 4OE	Active-Low Output Enables	Independent control per 4-bit group; enables granular bus segmentation and power gating.
V_CC (Pins 24, 48)	Power Supply	Dual V_CC pins reduce supply inductance and improve noise immunity across wide bus.
GND (Pins 1, 13, 25, 37)	Ground	Four dedicated GND pins minimize ground bounce and support clean return paths per quadrant.

Key Features

Feature	Design Value
I_off partial-power-down support	Enables safe integration into mixed-power-domain systems by blocking reverse current flow when V_CC is off.
Edge-rate controlled outputs	Reduces simultaneous switching noise (SSN) and EMI, improving signal integrity on shared buses and backplanes.
Flow-through pinout	Input and output pins aligned on opposite sides of package - simplifies layer routing and reduces vias in high-density layouts.
Low ground bounce (V_OLP < 1.0 V)	Maintains stable reference for adjacent logic, preventing false switching in tightly coupled digital systems.
Industrial temperature range	Validated operation from –40°C to +85°C ensures reliability in factory automation, telecom infrastructure, and embedded control.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74FCT162244CTPVCT	Balanced 24-mA drivers; includes current-limiting resistors; lower ground bounce (<0.6 V).	Optimized for transmission-line driving with reduced undershoot; less suitable for high-sink-load backplanes.	Select when driving controlled-impedance traces rather than lumped capacitive loads.
74FCT162H244CTPVCT	Includes bus-hold circuitry on all inputs; eliminates need for external pull-up/down resistors.	Preferred in systems with floating or unterminated inputs (e.g., hot-pluggable slots); adds ~100 µA input bias current.	Select when input signal integrity must be maintained without external biasing components.

Compared with 74FCT162244CTPVCT and 74FCT162H244CTPVCT, the 74FCT16244CTPVCTG4 offers highest sink drive (64 mA) and fastest propagation (4.1 ns), making it optimal for demanding backplane and memory interface roles where load strength and speed outweigh bus-hold or transmission-line optimization needs.

FAQ

What is the maximum operating frequency supported by the 74FCT16244CTPVCTG4?

The 74FCT16244CTPVCTG4 does not specify a maximum clock frequency directly, but its 4.1 ns maximum propagation delay (t_PLH/t_PHL) supports reliable operation in systems with data rates up to approximately 200 MHz under typical loading conditions. Actual usable frequency depends on board layout, load capacitance, and signal integrity margins - design validation is recommended for >100 MHz applications using the 74FCT16244CTPVCTG4.

Does the 74FCT16244CTPVCTG4 support hot-swap or live-insertion?

Yes - the 74FCT16244CTPVCTG4 incorporates I_off circuitry that limits current backflow to ±1 µA when V_CC = 0 V, enabling safe hot-swap operation in partially powered systems. This feature protects both the 74FCT16244CTPVCTG4 and upstream drivers during insertion/removal, provided all inputs remain within –0.5 V to +7.0 V absolute maximum ratings during transition.

What is the purpose of the four separate OE pins on the 74FCT16244CTPVCTG4?

The four active-low Output Enable (OE) pins - 1OE through 4OE - provide independent three-state control for each 4-bit buffer group. This allows selective isolation of bus segments, enabling dynamic partitioning (e.g., isolating memory vs. I/O regions), power gating of unused sections, and conflict-free multi-master arbitration - functionality essential in complex 74FCT16244CTPVCTG4-based bus architectures.

Can the 74FCT16244CTPVCTG4 be used with 3.3-V logic inputs?

No - the 74FCT16244CTPVCTG4 is a 5-V-only device with TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V). While 3.3-V CMOS outputs may exceed V_IH, they risk violating the minimum high-level input voltage under worst-case V_CC tolerance (4.5 V) and temperature. A level-shifter or 5-V-compatible driver is required upstream of the 74FCT16244CTPVCTG4 for guaranteed interoperability.

How does the flow-through pinout of the 74FCT16244CTPVCTG4 benefit PCB layout?

The flow-through pinout places inputs (A) and outputs (Y) on opposite sides of the SSOP-48 package, with enables (OE) and power (V_CC/GND) distributed across edges. This arrangement minimizes crossing traces, reduces layer count, avoids vias in critical signal paths, and improves signal integrity - especially valuable in space-constrained industrial PCBs where the 74FCT16244CTPVCTG4 serves as a high-density bus repeater.
