Product details
Overview
FCT162823CTPVCTG4 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 partial-power-down protection, and delivers typical VOLP <0.6 V and output skew <0.5 ns.
For engineers reviewing the FCT162823CTPVCTG4 datasheet, FCT162823CTPVCTG4 pinout, FCT162823CTPVCTG4 application, or FCT162823CTPVCTG4 equivalent, this page provides verified functional identity, SSOP-56 package mapping, timing-critical switching specs (tPLH/tPHL ≤6.0 ns), and real-world substitution guidance for transmission-line–focused logic interfacing.
Technical Context
The FCT162823CTPVCTG4 implements dual 9-bit registers synchronized by shared clock and clock-enable inputs, enabling 18-bit flow-through data latching. Its active-low asynchronous clear (CLR) and output enable (OE) support system-level reset and bus isolation.
It uses current-limiting resistors integrated into 24 mA balanced output drivers to suppress ground bounce and undershoot-eliminating need for external termination on controlled-impedance lines. Ioff circuitry ensures outputs enter high-impedance state during power-down, preventing backflow current.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit registered bus interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16823CTPVCT | Higher drive (64 mA sink / 32 mA source); no integrated current limiting; higher VOLP (≤1.0 V) | Better suited for heavy capacitive loads (e.g., >100 pF per line) but requires external termination for transmission lines | Select when driving unterminated backplanes or high-C bus stubs; avoid for impedance-controlled routing |
| SN74ALVTH162823DGGR | 3.3 V only (2.3–3.6 V), lower drive (24 mA), LVCMOS-compatible; no Ioff; different pinout | Designed for low-voltage, low-power portable instrumentation-not drop-in compatible with 5V systems | Choose only for new 3.3 V designs requiring reduced power; not a functional replacement for FCT162823CTPVCTG4 |

FAQ
What is the exact function of FCT162823CTPVCTG4 in a digital system?
The FCT162823CTPVCTG4 is an 18-bit, dual 9-bit bus interface register with independent clock enable and output enable controls. It latches parallel data on rising clock edges, provides three-state outputs for bus sharing, and features integrated current-limiting drivers optimized for transmission-line driving-making it ideal for high-integrity 5V parallel data paths in industrial controllers and test equipment.
Does FCT162823CTPVCTG4 support partial power-down, and how is it implemented?
Yes, FCT162823CTPVCTG4 supports partial power-down via its Ioff circuitry. When VCC = 0 V, output leakage remains ≤1 µA regardless of input/output voltage levels, preventing damaging current backflow during hot-swap or multi-rail sequencing. This behavior is guaranteed across −40°C to +85°C and is intrinsic to the device's silicon design-not dependent on external biasing.
What package type and footprint does FCT162823CTPVCTG4 use?
FCT162823CTPVCTG4 uses a 56-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 0.025-inch pitch. Its package drawing is DL, pin 1 identifier is marked in the top-left corner, and it complies with JEDEC MO-153. The device is RoHS-compliant with CU NIPDAU finish and MSL Level-1 rating for unlimited floor life at ≤30°C/60% RH.
How does FCT162823CTPVCTG4 differ from CY74FCT16823CTPVCT in output drive capability?
FCT162823CTPVCTG4 uses balanced 24 mA output drivers with integrated current-limiting resistors, yielding VOLP <0.6 V and enabling direct transmission-line drive. In contrast, CY74FCT16823CTPVCT delivers 64 mA sink / 32 mA source without current limiting, resulting in higher ground bounce (VOLP <1.0 V) and requiring external termination for clean signal integrity on controlled-impedance traces.
Can FCT162823CTPVCTG4 be used in place of FCT16823CTPVCT in an existing design?
No-FCT162823CTPVCTG4 and FCT16823CTPVCT are functionally distinct variants. While both are 18-bit registers in SSOP-56 packages, FCT162823CTPVCTG4 has balanced 24 mA drivers and lower ground bounce, whereas FCT16823CTPVCT offers asymmetric 64/32 mA drive. Substitution requires validation of load capacitance, termination scheme, and noise margin-no pin-to-pin or electrical drop-in compatibility is guaranteed.
