Product details

Overview

CY74FCT163501CPVC from Texas Instruments is an 18-bit registered bus transceiver with dual-directional latched/clock/transparent operation, 24 mA balanced output drive, 4.6 ns propagation delay (t_PLH/t_PHL), and 5V-tolerant I/O for mixed-voltage system interfacing in industrial backplane and memory subsystem applications.

For engineers reviewing the CY74FCT163501CPVC datasheet, CY74FCT163501CPVC pinout, CY74FCT163501CPVC application, or CY74FCT163501CPVC equivalent, key selection criteria include its SSOP-56 package, 2.7–3.6 V supply range, power-off disable for live insertion, edge-rate control for noise reduction, and compatibility with LCX/LPT logic families.

Technical Context

The CY74FCT163501CPVC integrates D-type latches and flip-flops to support three operational modes per direction: transparent (LEAB = HIGH), latch-on-level (LEAB = LOW + CLKAB static), or clocked edge-triggered (LEAB = LOW + CLKAB rising edge). Data flow is independently controlled for A-to-B and B-to-A paths via dedicated OE, LE, and CLK inputs.

Its 24 mA balanced drivers incorporate internal current-limiting resistors, reducing ground bounce (V_OLP < 0.6 V at V_CC = 3.3 V) and eliminating need for external termination on transmission lines. Power-off disable ensures high-impedance outputs when V_CC = 0 V, enabling hot-swap capability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - supports 3.3 V systems with ±0.3 V tolerance and compatibility with 2.5 V input thresholds.
Propagation Delay	4.6 ns max (A↔B) - enables reliable operation up to 150 MHz clock frequency in registered mode.
Output Drive	±24 mA - provides robust signal integrity on unterminated PCB traces up to 15 cm.
Input Voltage Tolerance	−0.5 V to +7.0 V - allows direct interface with 5 V TTL/CMOS without level shifters.
Operating Temperature	−40 °C to +85 °C - qualified for industrial environments including telecom line cards and motor control modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar registered bus transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY74FCT163H501CPVC	Includes bus-hold circuitry on all data inputs; higher input leakage (±100 µA vs. ±1 µA); no 5 V tolerance guarantee.	Eliminates external pull-ups in floating-bus scenarios but not recommended for rail-to-rail CMOS translation.	Select only if bus-hold functionality is required and 5 V tolerance is unnecessary.
SN74ALVCH163501GR	Lower V_CC range (1.65–3.6 V); 12 mA drive; no power-off disable; different pinout (64-pin RGY).	Suitable for low-power portable designs but incompatible for live-insertion or high-drive applications.	Choose only for battery-powered systems where 24 mA drive and hot-swap are not needed.

Compared with CY74FCT163H501CPVC and SN74ALVCH163501GR, the CY74FCT163501CPVC uniquely combines 5 V tolerance, 24 mA drive, power-off disable, and SSOP-56 packaging-making it the sole option for industrial backplane interfaces requiring all four features simultaneously.

FAQ

What is the maximum clock frequency supported by CY74FCT163501CPVC?

The CY74FCT163501CPVC supports a maximum clock frequency of 150 MHz for CLKAB or CLKBA inputs, as specified in its switching characteristics table under V_CC = 3.0–3.6 V conditions. This rating assumes proper load conditions and layout practices; actual system-level timing must account for board trace delays and signal integrity margins.

Does CY74FCT163501CPVC support live insertion into powered systems?

Yes, CY74FCT163501CPVC supports live insertion due to its power-off disable feature: when V_CC = 0 V, outputs automatically enter high-impedance state, preventing back-driving of active bus lines. This behavior is verified across the full industrial temperature range and is integral to its SSOP-56 mechanical design.

Is CY74FCT163501CPVC 5 V tolerant on all I/O pins?

Yes, CY74FCT163501CPVC has 5 V tolerant inputs and outputs, rated for DC input/output voltages from −0.5 V to +7.0 V. This allows direct connection to 5 V TTL/CMOS logic while operating from a 3.3 V supply, eliminating need for external level-shifting components in mixed-voltage designs.

What package type is used for CY74FCT163501CPVC?

CY74FCT163501CPVC uses a 56-pin SSOP (Shrunk Small Outline Package) with O56 designation, 300-mil body width, and 25-mil pitch. It complies with JEDEC MO-118 standard and is distinct from the TSSOP variant (Z56) used in other members of the same family.

How does CY74FCT163501CPVC reduce ground bounce compared to standard logic devices?

CY74FCT163501CPVC reduces ground bounce through integrated edge-rate control circuitry and 24 mA balanced output drivers with internal current-limiting resistors. Typical V_OLP (ground bounce) is < 0.6 V at V_CC = 3.3 V and T_A = 25 °C-verified by measurement, not simulation-enabling cleaner switching in dense PCB layouts.
