Product details
Overview
74FCT162374TPVCG4 from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit sections, designed for high-speed bus buffering in industrial systems. It features balanced 24 mA output drivers, 10 ns max propagation delay (CLK to O), Ioff partial-power-down support, and operates at 5V ±10% across −40°C to +85°C. Used in backplane interface and transmission-line driving applications.
For engineers reviewing the 74FCT162374TPVCG4 datasheet, 74FCT162374TPVCG4 pinout, 74FCT162374TPVCG4 application, or 74FCT162374TPVCG4 equivalent, key selection criteria include output drive strength (24 mA), ground bounce performance (<0.6 V), flow-through pinout for PCB routing, and SSOP-48 package compatibility with legacy 300-mil pitch layouts.
Technical Context
This device implements two independent 8-bit D-type registers sharing common clock and output-enable controls, enabling flexible 8- or 16-bit data latching. Its Ioff circuitry actively disables outputs during power-down to prevent current backflow, meeting industrial partial-power-down requirements.
The balanced 24 mA output drivers incorporate internal current-limiting resistors, reducing reliance on external termination and minimizing undershoot/ground bounce-critical for clean signal integrity on transmission lines and high-capacitance buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5 V ±10% - Ensures stable operation across industrial supply tolerances without regulation. |
| Propagation Delay | 10 ns max (CLK to O) - Supports 100 MHz system timing margins in synchronous bus interfaces. |
| Output Drive | ±24 mA - Provides sufficient current for driving 50-Ω transmission lines or unterminated stubs. |
| Ground Bounce | <0.6 V typical at VCC = 5 V - Reduces noise coupling into shared VCC/GND planes. |
| Ioff Support | Active at VCC = 0 V - Enables safe hot-insertion and multi-rail power sequencing. |
| Operating Temp | −40°C to +85°C - Qualified for extended industrial ambient conditions without derating. |
| Input Hysteresis | 100 mV - Improves noise immunity on slow or noisy control signals like OE/CLK. |
Pinout & Package
74FCT162374TPVCG4 is housed in a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 25-mil pitch, compliant with JEDEC MO-118. The flow-through pinout minimizes trace crossovers and supports compact PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low output enable (per 8-bit section) | Independent control of each 8-bit bank's three-state outputs; enables split-bus operation. |
| 1CLK, 2CLK | Positive-edge clock inputs (per section) | Edge-triggered sampling allows synchronous capture without additional latch logic. |
| 1D1–1D8, 2D1–2D8 | Data inputs (two 8-bit groups) | Direct connection to upstream data sources; no internal serialization/deserialization. |
| 1O1–1O8, 2O1–2O8 | Three-state outputs (two 8-bit groups) | 24 mA balanced drivers reduce need for external series termination on PCB traces. |
| VCC, GND (×4) | Power and ground terminals | Multiple VCC/GND pairs minimize switching noise and improve PSRR across the die. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced 24 mA outputs | Enables direct drive of 50-Ω transmission lines without external resistors, reducing BOM count and layout area. |
| Flow-through pinout | Input pins on one side and corresponding outputs on the opposite side simplify layer routing and reduce vias. |
| Ioff partial-power-down | Prevents back-current when VCC is off, supporting hot-swap and mixed-voltage system designs. |
| Low ground bounce (<0.6 V) | Maintains signal integrity in dense, high-speed digital systems by limiting simultaneous switching noise. |
| Edge-rate control | Reduces EMI emissions and improves noise margin without requiring external slew-rate limiting components. |

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 |
|---|---|---|---|
| CY74FCT162374ATPVC | 5.2 ns max propagation delay vs. 10 ns; otherwise identical electrical specs and pinout. | Suitable where tighter timing margins are required (e.g., >100 MHz clock domains). | Select CY74FCT162374ATPVC if system timing budget demands sub-6 ns register delay. |
| 74FCT162374CTPVCT | 6.5 ns max propagation delay; same SSOP-48 package and Ioff capability. | Offers intermediate speed grade for cost-sensitive designs where 10 ns is excessive. | Choose 74FCT162374CTPVCT when balancing performance, power, and procurement lead time. |
Compared with CY74FCT162374ATPVC and 74FCT162374CTPVCT, the 74FCT162374TPVCG4 provides the highest propagation delay tolerance (10 ns), making it optimal for relaxed timing constraints, lower EMI sensitivity, and legacy system drop-in replacement where speed headroom exists.

FAQ
What is the maximum clock frequency supported by the 74FCT162374TPVCG4?
The 74FCT162374TPVCG4 does not specify a maximum clock frequency directly, but its 10 ns maximum propagation delay (tPLH/tPHL) and 5 ns minimum clock pulse width (tW) imply reliable operation up to approximately 100 MHz in well-designed systems with adequate setup/hold margins. System-level timing must account for board trace delays and load capacitance.
Does the 74FCT162374TPVCG4 support hot-swap or partial-power-down operation?
Yes, the 74FCT162374TPVCG4 includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-insertion or mixed-rail power sequencing-making it suitable for modular industrial backplanes and field-replaceable units.
What is the purpose of separate 1OE and 2OE pins on the 74FCT162374TPVCG4?
The independent 1OE and 2OE pins allow selective three-state control of each 8-bit register section. This enables flexible bus partitioning-for example, holding one 8-bit channel active while tri-stating the other during multiplexed data transfers or fault isolation in redundant I/O systems.
How does the 74FCT162374TPVCG4 differ from the CY74FCT16374T series?
The 74FCT162374TPVCG4 uses balanced 24 mA output drivers optimized for transmission-line driving with low ground bounce (<0.6 V), whereas CY74FCT16374T offers higher 64 mA sink capability for heavy capacitive loads. Their pinouts and logic functions are identical, but drive strength and noise characteristics are tailored to different interconnect challenges.
Is the 74FCT162374TPVCG4 RoHS-compliant and lead-free?
Yes, the 74FCT162374TPVCG4 is Green (RoHS & no Sb/Br) compliant with CU NIPDAU lead finish and meets JEDEC Level-1 moisture sensitivity standards. It is rated for reflow soldering at peak temperatures up to 260°C and carries TI's industrial temperature qualification (−40°C to +85°C).
