Product details
Overview
74FCT162374ETPVG from Renesas Electronics is a 16-bit edge-triggered D-type register with dual 8-bit or unified 16-bit clock control, 3-state outputs, ±24mA balanced drive, 3.7ns max propagation delay (tPLH/tPHL), and industrial temperature range (–40°C to +85°C); used for high-speed data synchronization and bus buffering in backplane and board-level interfaces.
For engineers reviewing the 74FCT162374ETPVG datasheet, 74FCT162374ETPVG pinout, 74FCT162374ETPVG application, or 74FCT162374ETPVG equivalent, key selection criteria include output skew (<0.5ns), low ground bounce (<0.6V), TTL-compatible inputs, 5V ±10% supply operation, and TSSOP-48 green package compatibility.
Technical Context
The 74FCT162374ETPVG implements two independent 8-bit registers or one 16-bit register via shared clock (xCLK) and separate output enables (1OE/2OE), supporting flow-through pin layout for PCB routing efficiency. Its dual-metal CMOS process delivers fast switching with controlled edge rates and hysteresis-enhanced input noise immunity.
All 16 outputs feature current-limiting resistors and symmetrical drive strength (±24mA), minimizing system-level signal integrity issues such as ground bounce (VOLP < 0.6V) and undershoot-reducing or eliminating need for external series termination resistors on high-speed buses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74FCT162374CTPVG | Slower max speed: 5.2ns tPLH/tPHL vs. 3.7ns; same pinout, package, and function | Suitable for cost-sensitive designs where 25MHz–40MHz operation suffices | Select 74FCT162374CTPVG if timing margin allows relaxed propagation delay without sacrificing footprint or drive strength |
| SN74ALVTH16374GR | Different family: ALVT with 3.3V VCC, lower drive (±24mA only at 3.3V), no hysteresis, 48-TSSOP but non-RoHS legacy marking | Requires level translation when interfacing to 5V systems; lacks noise immunity for harsh environments | Choose SN74ALVTH16374GR only in pure 3.3V domains where voltage compatibility and RoHS are secondary to legacy sourcing |
Compared with 74FCT162374CTPVG and SN74ALVTH16374GR, the 74FCT162374ETPVG offers the fastest timing (3.7ns), built-in hysteresis, and guaranteed 5V operation-making it optimal for industrial-grade 16-bit bus interfaces demanding noise resilience and sub-4ns precision.

FAQ
What is the maximum clock frequency supported by the 74FCT162374ETPVG?
The 74FCT162374ETPVG supports clock frequencies up to approximately 270MHz, derived from its 3.7ns maximum propagation delay (tPLH/tPHL) and 3ns minimum clock pulse width (tW). This enables reliable operation in high-speed synchronous bus systems where setup and hold timing margins must be maintained across all 16 bits. The 74FCT162374ETPVG achieves this while maintaining sub-0.5ns output skew for deterministic parallel data capture.
Does the 74FCT162374ETPVG support mixed-voltage operation with 3.3V logic inputs?
Yes-the 74FCT162374ETPVG accepts 3.3V logic-high inputs directly due to its TTL-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) and integrated input hysteresis. It operates from a 5V supply (5.0V ±10%) and drives 5V-tolerant loads, making it suitable for interfacing 3.3V FPGAs or microcontrollers to 5V backplanes without external level shifters. The 74FCT162374ETPVG maintains full timing and drive specifications under these conditions.
How does the 74FCT162374ETPVG minimize ground bounce in high-speed applications?
The 74FCT162374ETPVG minimizes ground bounce through balanced ±24mA output drivers with integrated current-limiting resistors and a distributed 10-pin GND structure in its TSSOP-48 package. Measured VOLP is <0.6V at VCC = 5V and TA = 25°C, significantly reducing transient voltage spikes during simultaneous switching. This design eliminates the need for external series termination and prevents false triggering in adjacent logic-key for stable operation in the 74FCT162374ETPVG's target industrial and telecom applications.
Can the 74FCT162374ETPVG be configured as two independent 8-bit registers?
Yes-the 74FCT162374ETPVG supports dual 8-bit operation using separate clock inputs (1CLK, 2CLK) and independent output enables (1OE, 2OE). Each bank (1D1–1D8/1O1–1O8 and 2D1–2D8/2O1–2O8) functions autonomously, allowing asynchronous latching and 3-state control. This configuration is explicitly supported in the functional block diagram and timing tables of the official datasheet, and the 74FCT162374ETPVG pinout reflects this partitioned architecture.
Is the 74FCT162374ETPVG pin-compatible with the older 74FCT16374 series?
Yes-the 74FCT162374ETPVG is a plug-in replacement for the 74FCT16374 series, as confirmed in the original IDT datasheet: "The FCT162374T are plug-in replacements for the FCT16374T and ABT16374 for on-board bus interface applications." Both share identical TSSOP-48 pinout, function table, and DC/AC electrical characteristics, enabling drop-in upgrades with improved skew (<0.5ns vs. typical 1ns) and lower ground bounce. The 74FCT162374ETPVG retains full backward compatibility while enhancing signal integrity.
