Product details
Overview
74FCT162823CTPVCT from Texas Instruments is an 18-bit bus interface register with balanced 24 mA output drivers, designed for high-speed transmission-line driving in industrial systems. It operates at 5V ±10%, supports −40°C to +85°C ambient, features Ioff for partial-power-down mode, and delivers typical ground bounce <0.6 V at VCC = 5 V, TA = 25°C.
For engineers reviewing the 74FCT162823CTPVCT datasheet, 74FCT162823CTPVCT pinout, 74FCT162823CTPVCT application, or 74FCT162823CTPVCT equivalent, key selection considerations include its 6 ns max propagation delay (CLK to Q), 24 mA balanced drive capability, SSOP-56 package, flow-through pinout for PCB layout simplification, and support for noise-sensitive backplane and point-to-point interconnect applications.
Technical Context
The 74FCT162823CTPVCT implements dual 9-bit registers with shared control lines (CLK, CLKEN, CLR, OE) enabling 18-bit synchronized latching. Its edge-rate controlled outputs reduce system switching noise and eliminate need for external termination resistors.
It integrates Ioff circuitry that disables outputs during power-down to prevent current backflow, and uses current-limiting resistors in each output stage to minimize undershoot and ground bounce-critical for clean signal integrity on transmission lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - compatible with standard TTL/CMOS logic rails and industrial 5V systems |
| Propagation Delay (CLK→Q) | Max 6.0 ns at CL=50 pF - enables reliable operation in ≥160 MHz clock domains |
| Output Drive | 24 mA balanced sink/source - provides matched impedance drive for controlled-impedance traces without external resistors |
| Ground Bounce (VOLP) | Typ <0.6 V at VCC=5 V, TA=25°C - ensures stable reference for adjacent inputs in dense layouts |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded and communications equipment |
| Ioff Support | Active at VCC=0 V - prevents damaging back-current during hot-insertion or partial power-down sequences |
| ESD Rating | >2000 V HBM - meets industrial handling robustness requirements without additional protection circuitry |
Pinout & Package
74FCT162823CTPVCT is housed in a 56-pin SSOP (Shrink Small Outline Package), 300-mil body width, JEDEC MO-118 compliant, with 0.025-inch pitch. Pin count and physical dimensions match industry-standard 56-pin SSOP footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1CLR, 2CLR | Asynchronous Clear (Active LOW) | Resets all 18 outputs to LOW independently of clock; enables fast system initialization |
| 1CLK, 2CLK | Clock Inputs | Edge-triggered sampling of D inputs; dual-clock structure supports staggered or mirrored timing domains |
| 1CLKEN, 2CLKEN | Clock Enable (Active LOW) | Gates clock propagation-allows dynamic clock gating without glitch risk |
| 1OE, 2OE | Output Enable (Active LOW) | Three-state control per 9-bit bank; enables bus sharing and isolation between subsystems |
| D1–D18 | Data Inputs | 18 parallel CMOS/TTL-compatible inputs; hysteresis (100 mV) improves noise immunity on slow-rising signals |
| Q1–Q18 | Three-State Outputs | 18 low-skew (<0.5 ns), edge-rate-controlled outputs; flow-through routing minimizes trace crossovers |
| VCC, GND | Power & Ground | Dual VCC/GND pairs per half-bank reduce simultaneous switching noise and improve PSRR |
Key Features
| Feature | Design Value |
|---|---|
| Balanced 24 mA output drivers | Enables direct drive of 50 Ω transmission lines without series termination, reducing BOM count and layout area |
| Edge-rate control circuitry | Actively limits dV/dt to suppress harmonic content and crosstalk in high-density routing environments |
| Typical output skew <0.5 ns | Guarantees tight timing alignment across all 18 outputs-critical for parallel data capture and DDR-style interfaces |
| Ioff partial-power-down support | Prevents back-driving and latch-up when VCC is off but bus remains active-essential for hot-swap and modular systems |
| Flow-through pinout | Input pins on one side, outputs on opposite side-enables straight-layer PCB routing and eliminates vias in critical signal paths |
Applications
| High-Speed Backplane Interface | Industrial PLC I/O Module |
|---|---|

IC Role / Device Role / Timing Role: High-fidelity waveform register staging test patterns with minimal jitter and deterministic edge placement. Use Value: 6 ns max propagation delay and edge-rate control ensure sub-nanosecond timing accuracy across all 18 bits-meeting Class III ATE timing margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT162823CTPVC | Same die, identical electrical specs; differs only in tape-and-reel packaging (20-unit vs. 1000-unit reel) | No functional difference; suited for prototyping or low-volume validation where smaller reels reduce inventory overhead | Select when evaluating or qualifying the device before committing to full production reels |
| 74FCT162823ATPACT | Slower speed grade: 10 ns max CLK→Q delay vs. 6 ns; TSSOP-56 package instead of SSOP-56 | Lower performance margin; suitable for cost-sensitive designs where timing slack exceeds 4 ns and board space favors TSSOP | Choose only if timing budget permits 4 ns additional delay and footprint constraints favor 240-mil TSSOP over 300-mil SSOP |
Compared with CY74FCT162823CTPVC, the 74FCT162823CTPVCT offers identical functionality in a higher-volume reel format optimized for automated SMT production; compared with 74FCT162823ATPACT, it delivers 4 ns tighter timing and SSOP mechanical compatibility with legacy 300-mil socketed designs.

FAQ
What is the maximum clock frequency supported by the 74FCT162823CTPVCT?
The 74FCT162823CTPVCT has a maximum propagation delay of 6.0 ns (CLK to Q) under CL = 50 pF conditions. This supports reliable operation up to approximately 160 MHz in well-designed systems with adequate setup/hold margins. Actual usable frequency depends on board layout, load capacitance, and system-level timing constraints-not specified as a standalone clock frequency rating in the datasheet.
Does the 74FCT162823CTPVCT support hot-swap or partial-power-down operation?
Yes, the 74FCT162823CTPVCT includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap or partial-power-down scenarios. This feature is fully characterized per JEDEC JESD78 and enables safe use in modular systems where boards may be inserted or removed while the backplane remains powered.
What package type and dimensions does the 74FCT162823CTPVCT use?
The 74FCT162823CTPVCT uses a 56-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 0.025-inch lead pitch, conforming to JEDEC MO-118. Its mechanical outline measures 18.29 mm × 7.39 mm × 2.29 mm (L × W × H), and it is RoHS-compliant with Green (Pb-free, no Sb/Br) finish and MSL Level-1 rating.
How does the 74FCT162823CTPVCT differ from the CY74FCT16823T series?
The 74FCT162823CTPVCT features balanced 24 mA output drivers with integrated current-limiting resistors, optimized for transmission-line driving with minimal ground bounce (<0.6 V). In contrast, the CY74FCT16823T offers asymmetric 64 mA sink / 32 mA source drive, targeting high-capacitance loads and backplanes-making the 74FCT162823CTPVCT better suited for controlled-impedance interconnects.
Can the 74FCT162823CTPVCT be used with 3.3 V logic interfaces?
No-the 74FCT162823CTPVCT is strictly a 5 V device (VCC = 5 V ±10%) and is not 3.3 V tolerant. Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) are TTL-compatible but require 5 V supply for correct output voltage levels (VOH ≥ 2.4 V, VOL ≤ 0.55 V). Interfacing with 3.3 V systems requires level-shifting circuitry or a 3.3 V–compatible alternative.
