Product details

Overview

74FCT162374CTPACT from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 5.2 ns propagation delay (CLK to O), 24 mA balanced output drivers, and Ioff partial-power-down support. It operates at 5V ±10% across −40°C to +85°C and is used for high-speed bus buffering in transmission-line-driven systems.

For engineers reviewing the 74FCT162374CTPACT datasheet, 74FCT162374CTPACT pinout, 74FCT162374CTPACT application, or 74FCT162374CTPACT equivalent, key selection criteria include its 24 mA balanced drive strength, sub-0.6 V ground bounce (VOLP), flow-through pinout for PCB layout simplification, and TSSOP-48 package compatibility with high-density routing.

Technical Context

The 74FCT162374CTPACT implements two independent 8-bit registers or one unified 16-bit register via shared CLK and OE inputs. Its edge-rate controlled outputs reduce system switching noise and eliminate need for external termination resistors on transmission lines.

It features Ioff circuitry that disables outputs during power-down to prevent backflow current, and uses current-limiting resistors integrated into 24 mA balanced output drivers-enabling clean signal integrity with minimal undershoot and reduced ground bounce under dynamic load conditions.

Key Specifications

tPLH / tPHL	2.0–5.2 ns - enables high-speed synchronous data latching in ≤200 MHz clock domains
Output Drive	±24 mA - balanced sourcing/sinking supports terminated transmission-line driving without external resistors
VOLP (Ground Bounce)	<0.6 V at VCC = 5 V, TA = 25°C - ensures stable low-state integrity during simultaneous switching
Operating Temp	−40°C to +85°C - qualified for industrial-grade embedded control and communications equipment
Ioff Support	Active at VCC = 0 V - prevents damaging current backflow during hot-insertion or partial power-down sequences

Pinout & Package

74FCT162374CTPACT is housed in a 48-pin Thin Shrunk Small Outline Package (TSSOP) per JEDEC MO-153, with 0.5 mm pitch, 12.6 mm × 6.2 mm body, and 1.2 mm max height. Pin 1 identifier located at top-left corner with beveled edge marking.

Pin/Terminal	Circuit Role	Design Meaning
1–8, 17–24, 25–32, 41–48	Data Inputs (D1–D8 for Channel 1 & 2; D1–D8 for Channel 2)	Asynchronous parallel data inputs accepting TTL/CMOS logic levels; each channel has dedicated 8-bit input bank
9, 26	CLK (Clock Inputs)	Positive-edge-triggered clock for respective 8-bit register sections; enables synchronous capture of input data
10, 27	OE (Output Enable, Active LOW)	Three-state control per 8-bit channel; asserts high-impedance output when HIGH, enabling bus sharing
11–16, 19–24, 33–40	Outputs (O1–O8 for Channel 1 & 2)	24 mA balanced CMOS/TTL-compatible outputs with edge-rate control; flow-through arrangement minimizes trace crossovers
18, 31, 44	GND	Dedicated ground pins per functional block - reduces ground bounce and improves noise immunity
12, 29, 45	VCC	Power supply pins distributed across package - lowers IR drop and enhances supply decoupling effectiveness

Key Features

Feature	Design Value
24 mA Balanced Output Drivers	Eliminates need for external series termination on PCB traces, reducing BOM count and layout complexity for point-to-point or stubbed transmission lines
Ioff Partial-Power-Down Support	Prevents backflow current when VCC = 0 V, enabling safe operation in hot-swap or multi-rail power sequencing environments
Flow-Through Pinout	Input-to-output signal path alignment across package halves simplifies layer stackup and reduces vias in high-speed routing
Edge-Rate Controlled Outputs	Minimizes EMI and crosstalk in dense interconnects by limiting slew rate without compromising timing performance
Low Ground Bounce (VOLP < 0.6 V)	Maintains logic-low margin under full 16-bit simultaneous switching, critical for reliable sampling in downstream receivers

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY74FCT16374CTPACT	64 mA sink / 32 mA source drive; higher ground bounce (VOLP <1.0 V); no output current limiting resistors	Better suited for heavy capacitive loads (e.g., backplanes >100 pF), less ideal for transmission-line driving	Select when driving high-C bus structures rather than controlled-impedance lines
74FCT162374ATPACT	6.5 ns propagation delay; otherwise identical architecture, drive strength, and Ioff behavior	Suitable for lower-speed designs where 5.2 ns timing margin is unnecessary	Choose for cost-sensitive industrial controls where 1.3 ns slower timing is acceptable

FAQ

What is the maximum clock frequency supported by the 74FCT162374CTPACT?

The 74FCT162374CTPACT has a minimum CLK pulse width of 3.3 ns (HIGH or LOW), supporting theoretical maximum clock frequencies up to ~150 MHz in ideal conditions. Real-world operation depends on setup/hold timing margins, PCB trace lengths, and load capacitance-but the device is routinely deployed in 80–100 MHz synchronous bus applications with verified timing closure.

Does the 74FCT162374CTPACT support hot-swap or partial-power-down operation?

Yes, the 74FCT162374CTPACT integrates Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap events or multi-rail power sequencing. This feature is fully specified over −40°C to +85°C and requires no external components to implement safe partial-power-down behavior in the 74FCT162374CTPACT.

What is the purpose of the current-limiting resistors inside the 74FCT162374CTPACT output drivers?

The internal current-limiting resistors in the 74FCT162374CTPACT's 24 mA balanced drivers reduce the need for external series termination, minimize undershoot on transmission lines, and suppress ground bounce (VOLP < 0.6 V). They provide inherent impedance matching for typical PCB trace impedances (50–75 Ω), improving signal fidelity without adding discrete components to the 74FCT162374CTPACT design.

Can the 74FCT162374CTPACT be used as two independent 8-bit registers?

Yes, the 74FCT162374CTPACT contains two functionally independent 8-bit register sections (Channels 1 and 2), each with dedicated CLK and OE inputs. By applying separate clocks and output enables, designers can operate them as isolated 8-bit latches-enabling flexible data staging, dual-bus interfacing, or staggered sampling within a single 74FCT162374CTPACT package.

Is the 74FCT162374CTPACT RoHS-compliant and lead-free?

Yes, the 74FCT162374CTPACT is manufactured with Green (RoHS & no Sb/Br) eco plan, featuring CU NIPDAU lead finish and JEDEC Level-1 moisture sensitivity rating. It complies with RoHS Directive 2011/65/EU and is suitable for lead-free reflow processes up to 260°C peak temperature-fully documented in TI's packaging addendum for the 74FCT162374CTPACT.
