Product details

Overview

74FCT162374ATPVCT from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 24 mA balanced output drivers, 6.5 ns max propagation delay (CLK to O), and I_off partial-power-down support. It operates at 5 V ±10% across −40°C to +85°C and is used for high-speed bus interfacing and transmission-line driving in industrial control backplanes.

For engineers reviewing the 74FCT162374ATPVCT datasheet, 74FCT162374ATPVCT pinout, 74FCT162374ATPVCT application, or 74FCT162374ATPVCT equivalent, key selection criteria include output drive symmetry (24 mA sink/source), ground bounce performance (<0.6 V typical VOLP), flow-through pinout for PCB layout simplification, and SSOP-48 packaging compatibility with automated assembly.

Technical Context

This device implements two independent 8-bit registers or one unified 16-bit register via shared CLK and OE inputs. Its balanced 24 mA output drivers incorporate internal current-limiting resistors to reduce external termination needs and suppress undershoot.

The I_off circuitry disables outputs during power-down to prevent damaging current backflow, and edge-rate control circuitry improves noise immunity. Output skew is specified at ≤0.5 ns between any two outputs switching in the same direction.

Key Specifications

Propagation Delay	6.5 ns max (CLK to O) - Enables reliable timing in 150+ MHz bus systems
Output Drive	±24 mA - Balanced sink/source capability minimizes ground bounce and supports transmission-line driving
Operating Temperature	−40°C to +85°C - Industrial-grade thermal range for embedded control and automation
I_off Support	Yes - Prevents backflow current during partial power-down, critical for hot-swap and low-power standby modes
Package	SSOP-48 (DL drawing) - 300-mil body width, JEDEC MO-118 compliant, suitable for high-density routing
VOLP (Ground Bounce)	<0.6 V typical at V_CC = 5 V, T_A = 25°C - Reduces signal integrity risk in multi-load parallel buses

Pinout & Package

74FCT162374ATPVCT is housed in a 48-pin Shrink Small Outline Package (SSOP), JEDEC MO-118 compliant, with 300-mil body width and 0.025-inch pitch. Pin 1 is located in Quadrant Q1 per tape-and-reel documentation.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-low three-state output enable	Independent control of each 8-bit register's output drivers; enables bus sharing without contention
1CLK, 2CLK	Positive-edge clock input	Registers data on rising edge; allows synchronous latching of two independent data streams
1D1–1D8, 2D1–2D8	Data inputs	Flow-through arrangement aligns inputs and outputs on opposite sides for minimal trace length and crosstalk reduction
1O1–1O8, 2O1–2O8	Three-state outputs	24 mA balanced drivers eliminate need for external series termination in point-to-point or stubbed transmission lines
V_CC, GND	Power supply pins	Dual V_CC/GND pairs per register block reduce simultaneous switching noise and improve PSRR

Key Features

Feature	Design Value
Balanced 24 mA output drivers	Reduces ground bounce to <0.6 V and eliminates external termination resistors in most transmission-line applications
I_off partial-power-down protection	Prevents backflow current when V_CC = 0 V, enabling safe integration into hot-pluggable or mixed-voltage subsystems
Flow-through pinout	Minimizes PCB trace length and layer transitions, lowering parasitic inductance and improving signal integrity
Edge-rate controlled outputs	Suppresses EMI generation and improves noise margin in electrically noisy industrial environments
Industrial temperature range	Ensures stable timing and drive strength across full −40°C to +85°C ambient, validated per JEDEC JESD22-A104

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY74FCT162374CTPVCT	5.2 ns max propagation delay; identical pinout, package, and drive strength	Higher speed grade suitable for >160 MHz bus timing closure where 6.5 ns is marginal	Select when system-level timing budget requires tighter propagation delay margin
74FCT162374ATPACT	TSSOP-48 (DGG) package; same electrical specs but 240-mil body width and 0.020-inch pitch	Preferred for high-density PCBs where SSOP-48 footprint is too wide for routing constraints	Select when board area is constrained and fine-pitch assembly capability is available

Compared with CY74FCT162374CTPVCT, the 74FCT162374ATPVCT trades 1.3 ns of propagation delay for broader availability and mature supply chain stability; compared with 74FCT162374ATPACT, it offers easier manual inspection and rework due to larger SSOP pitch, at the cost of 8 mm wider board footprint.

FAQ

What is the maximum clock frequency supported by the 74FCT162374ATPVCT?

The 74FCT162374ATPVCT does not specify a maximum clock frequency directly, but its 6.5 ns maximum propagation delay (t_PLH/t_PHL) and 5.0 ns minimum clock pulse width (t_W) imply reliable operation up to approximately 150 MHz in well-terminated systems. System-level timing must also account for setup (2.0 ns) and hold (1.5 ns) requirements relative to the clock edge.

Does the 74FCT162374ATPVCT support mixed-voltage operation between 3.3 V and 5 V logic domains?

No, the 74FCT162374ATPVCT is a 5 V-only device with V_CC = 5 V ±10% and input thresholds referenced to 5 V (VIH = 2.0 V min, VIL = 0.8 V max). It is not designed for 3.3 V input compatibility; level-shifting circuitry is required when interfacing with 3.3 V controllers or peripherals.

How does the I_off feature function in the 74FCT162374ATPVCT during power-down sequences?

The I_off circuitry in the 74FCT162374ATPVCT actively disables all outputs when V_CC drops below ~0.5 V, limiting leakage current to ±1 µA even if input or output pins remain biased at valid logic levels. This prevents damaging backflow current through the device during partial power-down, a requirement in hot-swap and modular power architectures.

Can the 74FCT162374ATPVCT be used as two independent 8-bit registers, and how is this configured?

Yes, the 74FCT162374ATPVCT can operate as two independent 8-bit registers. Connect 1CLK and 1OE to control the first byte (1D1–1D8 → 1O1–1O8), and 2CLK and 2OE to control the second byte (2D1–2D8 → 2O1–2O8). The flow-through pinout places inputs and outputs on opposite sides, simplifying routing for separate byte lanes.

What is the significance of the "AT" speed grade in the 74FCT162374ATPVCT part number?

The "AT" suffix in 74FCT162374ATPVCT denotes the 6.5 ns propagation delay speed grade-faster than the standard "T" grade (10.0 ns) but slower than the "CT" grade (5.2 ns). This grade balances timing margin, power consumption (ICCD = 60–100 µA/MHz), and noise performance for mid-speed industrial bus applications.
