Product details

Overview

74FCT16374CTPVCG4 from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 5.2 ns propagation delay (t_PLH/t_PHL), ±10% 5 V supply tolerance, and industrial −40°C to +85°C operation. It features 64 mA sink / 32 mA source drive strength and supports high-speed bus buffering in backplane and memory interface applications.

For engineers reviewing the 74FCT16374CTPVCG4 datasheet, 74FCT16374CTPVCG4 pinout, 74FCT16374CTPVCG4 application, or 74FCT16374CTPVCG4 equivalent, key selection criteria include output drive capability (64 mA sink), low ground bounce (<1.0 V VOLP), flow-through pinout for PCB layout simplification, and I_off support for partial-power-down mode operation.

Technical Context

This device implements two independent 8-bit registers or one unified 16-bit register via shared CLK and OE inputs. Its TTL-compatible input thresholds (V_IL = 0.8 V, V_VIH = 2.0 V) and CMOS-level outputs enable mixed-logic interfacing. The I_off circuitry actively disables outputs during power-down to prevent backflow current.

Designed for high-capacitance load driving, it delivers 64 mA sink current per output with typical ground bounce <1.0 V at V_CC = 5 V and T_A = 25°C. Output skew is specified at <250 ps, and clock pulse width requirement is only 3.3 ns minimum - enabling reliable operation in fast synchronous buses.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation Delay	2.0–5.2 ns (CLK to O); enables ≤200 MHz register clocking in timing-critical bus interfaces
Output Drive	64 mA sink / 32 mA source per pin; sufficient to drive heavy capacitive loads and unterminated transmission lines
Supply Voltage	5 V ±10%; operates reliably across wide industrial rail tolerances without external regulation
Operating Temperature	−40°C to +85°C; qualified for industrial-grade embedded control and communications equipment
Input Hysteresis	100 mV; improves noise immunity on slow-rising or noisy control signals like OE and CLK
Ground Bounce (VOLP)	<1.0 V at V_CC = 5 V, T_A = 25°C; reduces signal integrity risk in dense multi-output switching
I_off Support	Enabled; prevents damaging current backflow when V_CC = 0 V, critical for hot-swap and partial-power-down systems

Pinout & Package

74FCT16374CTPVCG4 is housed in a 48-pin SSOP (Shrink Small Outline Package), JEDEC MO-118 compliant, with 300-mil body width (18.29 mm × 7.39 mm), 0.630-inch length, and 0.050-inch pitch (1.27 mm). Pin 1 identifier located at top-left corner with beveled corner marking.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-low three-state output enable	Independent control of two 8-bit output groups; enables dynamic bus partitioning and contention avoidance
1CLK, 2CLK	Positive-edge clock inputs	Edge-triggered latching on rising transition; supports asynchronous clocking of two register banks
1D1–1D8, 2D1–2D8	Data inputs	16 total TTL/CMOS-compatible inputs; flow-through arrangement minimizes trace crossovers on PCB
1O1–1O8, 2O1–2O8	Three-state outputs	High-drive, low-skew outputs with I_off protection; compatible with 50 Ω transmission lines
V_CC, GND	Power and ground terminals	Dual V_CC/GND pairs (pins 24/25, 47/48) reduce simultaneous switching noise and improve PDN stability

Key Features

Feature	Design Value
Flow-through pinout	Input-to-output signal path alignment simplifies layer routing and reduces stub lengths in high-speed layouts
I_off partial-power-down	Outputs disabled with zero current backflow when V_CC = 0 V - essential for hot-plug and power-gated subsystems
Edge-rate control	Internally limited output slew rate suppresses EMI and system-level switching noise without external RC networks
Low ground bounce	VOLP <1.0 V ensures clean logic thresholds under full 16-bit switching, preserving timing margins in shared return paths
Industrial temperature range	−40°C to +85°C qualification guarantees stable setup/hold timing and drive strength across environmental extremes

FAQ

What is the maximum clock frequency supported by the 74FCT16374CTPVCG4?

The 74FCT16374CTPVCG4 has a minimum clock pulse width of 3.3 ns (high or low), supporting theoretical maximum clock frequencies up to ~300 MHz. However, real-world timing depends on setup/hold (2.0 ns / 1.5 ns), propagation delay (2.0–5.2 ns), and board-level signal integrity. For reliable operation with margin, 150–200 MHz is typical in well-designed industrial backplane systems using the 74FCT16374CTPVCG4.

Does the 74FCT16374CTPVCG4 support hot-swap or partial-power-down operation?

Yes, the 74FCT16374CTPVCG4 integrates I_off circuitry that disables outputs when V_CC = 0 V, preventing damaging current backflow from live buses into the unpowered device. This feature is explicitly characterized and guaranteed across the industrial temperature range, making the 74FCT16374CTPVCG4 suitable for hot-pluggable modules and power-gated subsystems.

What is the difference between 74FCT16374CTPVCG4 and 74FCT162374CTPVCG4?

The 74FCT16374CTPVCG4 provides asymmetric 64 mA sink / 32 mA source drive optimized for driving heavy capacitive loads and backplanes, while the 74FCT162374CTPVCG4 uses balanced 24 mA drivers with lower ground bounce (<0.6 V) for transmission-line applications. They share pinout and package but differ in drive architecture, noise performance, and target use cases - the 74FCT16374CTPVCG4 is not a drop-in replacement for the 74FCT162374CTPVCG4 in impedance-controlled designs.

Is the 74FCT16374CTPVCG4 RoHS-compliant and lead-free?

Yes, the 74FCT16374CTPVCG4 is RoHS-compliant and lead-free, with "Green (RoHS & no Sb/Br)" eco-plan designation, CU NIPDAU lead finish, and JEDEC Level-1 MSL rating (260°C peak reflow). It meets all six RoHS substance restrictions, including lead ≤0.1% by weight, and is qualified for standard lead-free reflow profiles without special handling requirements.

Can the 74FCT16374CTPVCG4 be used as two independent 8-bit registers?

Yes, the 74FCT16374CTPVCG4 contains two functionally independent 8-bit register banks (Bank 1: pins 1D1–1O8; Bank 2: pins 2D1–2O8), each with dedicated clock (1CLK/2CLK) and output enable (1OE/2OE) inputs. This allows concurrent or asynchronous latching of two 8-bit data streams - a capability confirmed in the functional description and pin configuration diagrams of the official datasheet for the 74FCT16374CTPVCG4.
