Product details

Overview

74FCT162245CTPVCT from Texas Instruments is a 16-bit bidirectional transceiver with balanced 24-mA output drivers, I_off partial-power-down support, and industrial-grade operation (–40°C to +85°C) at V_CC = 5V ±10%. It enables low-noise, high-speed data transfer between synchronous buses in backplane and transmission-line applications.

For engineers reviewing the 74FCT162245CTPVCT datasheet, 74FCT162245CTPVCT pinout, 74FCT162245CTPVCT application, or 74FCT162245CTPVCT equivalent, key selection criteria include its 4.1-ns max propagation delay, 24-mA balanced drive capability, ground-bounce reduction (<0.6V), TSSOP/SSOP package compatibility, and bus-isolation behavior under OE/DIR control.

Technical Context

This device operates as either two independent 8-bit transceivers or one unified 16-bit unit, with direction controlled by DIR and three-state output enabled by active-low OE. Its I_off circuitry ensures no backflow current during power-down, meeting industrial partial-power-down requirements.

Output drivers integrate current-limiting resistors to minimize undershoot and eliminate need for external termination on transmission lines. Electrical characteristics are fully specified across –40°C to +85°C, with input hysteresis (100 mV) and ESD robustness (>2000 V) confirmed per MIL-STD-883.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5 V ±10% - Ensures stable operation across industrial supply tolerances without regulation.
Max Propagation Delay	4.1 ns (A↔B) - Enables ≤244 MHz bus timing margin in synchronous systems.
Output Drive	±24 mA balanced - Supports driving 50-Ω transmission lines without external termination.
Ground Bounce (V_OLP)	<0.6 V at V_CC = 5 V - Reduces noise coupling into shared ground planes.
I_off Support	Yes - Prevents damaging current flow when V_CC = 0 V and I/O pins see voltage.
Operating Temperature	–40°C to +85°C - Validated for industrial ambient conditions without derating.
Input Hysteresis	100 mV - Improves noise immunity on slow-rising or noisy control signals (DIR/OE).

Pinout & Package

74FCT162245CTPVCT is housed in a 48-lead SSOP (O48) package, 300-mil body width, 25-mil lead pitch, with exposed pad not present. Pin numbering follows standard top-view orientation with pin 1 marked by notch or dot.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction Control Input (per 8-bit section)	Determines data flow direction: LOW = B→A, HIGH = A→B; controls internal bus switches.
1OE, 2OE	Output Enable Input (active LOW, per section)	Enables three-state outputs when LOW; places A/B ports in high-Z when HIGH.
1A1–1A8, 2A1–2A8	Port A I/O terminals	Bi-directional data interface for first/second octal bus; driven or sensed based on DIR/OE state.
1B1–1B8, 2B1–2B8	Port B I/O terminals	Bi-directional data interface for complementary bus; electrically isolated from Port A when OE HIGH.
V_CC (pins 24, 25, 47, 48)	Power Supply	Four dedicated V_CC pins reduce switching noise and improve PSRR across wideband operation.
GND (pins 12, 13, 26, 27, 39, 40)	Ground Reference	Six GND pins provide low-inductance return paths, critical for minimizing ground bounce in high-speed switching.

Key Features

Feature	Design Value
Balanced ±24-mA output drivers	Enables matched rise/fall times and reduced EMI on controlled-impedance traces.
Integrated current-limiting resistors	Eliminates need for discrete series termination, saving PCB area and BOM cost.
I_off partial-power-down protection	Allows safe hot-insertion and multi-rail sequencing without external isolation circuitry.
Edge-rate control circuitry	Reduces simultaneous switching noise (SSN) and improves signal integrity on dense boards.
Typical output skew <250 ps	Ensures deterministic timing alignment across all 16 bits for parallel bus capture.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74FCT162245CPAG	Same 24-mA drive, identical pinout, but in 48-pin TSSOP (Z48) with 240-mil width and 19.6-mil pitch.	Requires PCB layout change due to smaller footprint and tighter pitch; better for space-constrained designs.	Select when board real estate is limited and reflow profile supports fine-pitch TSSOP.
74FCT162H245CTPVCT	Adds bus-hold circuitry on all A/B inputs; otherwise identical speed, drive, and package.	Eliminates external pull-up/down resistors on floating inputs; preferred in systems with intermittent bus activity.	Select when input stability during tri-state or power-down states is critical and bus hold is required.

Compared with 74FCT162245CTPVCT, SN74FCT162245CPAG offers identical electrical performance in a smaller TSSOP package requiring layout revision, while 74FCT162H245CTPVCT adds bus-hold functionality without altering timing or drive-making it a drop-in upgrade only where input retention is needed.

FAQ

What is the maximum operating frequency supported by the 74FCT162245CTPVCT?

The 74FCT162245CTPVCT does not specify a maximum clock frequency directly, but its 4.1-ns maximum propagation delay (t_PLH/t_PHL) supports reliable operation in synchronous systems with bus cycle times ≥8.2 ns-equivalent to a theoretical upper limit of ~122 MHz for single-data-rate transfers. Actual achievable frequency depends on board layout, load capacitance, and timing margins set by system-level setup/hold requirements.

Does the 74FCT162245CTPVCT support hot-swap or live-insertion scenarios?

Yes-the 74FCT162245CTPVCT supports hot-swap operation via its I_off circuitry, which disables outputs and blocks current backflow when V_CC = 0 V while I/O pins remain biased. This prevents damage during live insertion into powered backplanes, provided voltage on A/B pins stays within –0.5 V to +7.0 V and no more than one output is shorted at a time.

Can the 74FCT162245CTPVCT be used as two independent 8-bit transceivers?

Yes-the 74FCT162245CTPVCT is internally partitioned into two independent 8-bit sections (1A/1B/1DIR/1OE and 2A/2B/2DIR/2OE), each with separate direction and output-enable controls. This allows concurrent bidirectional data transfer across two distinct buses without crosstalk, verified in the functional description and pin configuration diagrams.

What is the purpose of the six GND pins on the 74FCT162245CTPVCT SSOP package?

The six GND pins on the 74FCT162245CTPVCT serve to minimize ground inductance and distribute return current across high-frequency switching events. With 16 bidirectional outputs capable of 24-mA transitions, multiple low-inductance GND paths reduce ground bounce (V_OLP <0.6 V) and improve overall signal integrity-confirmed in the device's electrical characteristics and layout recommendations.

How does the 74FCT162245CTPVCT differ from the CY74FCT16245T variant?

The 74FCT162245CTPVCT features balanced ±24-mA output drivers with integrated current-limiting resistors for transmission-line driving, whereas the CY74FCT16245T provides asymmetric drive (64-mA sink / 32-mA source) optimized for high-capacitance loads and backplanes. Their pinouts and logic functions are identical, but drive strength, ground bounce, and target interconnect types differ significantly.
