Product details

Overview

74FCT162244ATPVC from Texas Instruments is a 16-bit non-inverting 3-state buffer/line driver with balanced 24-mA output drivers, designed for high-speed transmission-line driving in industrial bus interfaces. It operates at 5V ±10%, supports –40°C to +85°C ambient, features I_off for partial-power-down mode, and delivers typical output skew <250 ps.

For engineers reviewing the 74FCT162244ATPVC datasheet, 74FCT162244ATPVC pinout, 74FCT162244ATPVC application, or 74FCT162244ATPVC equivalent, key selection criteria include its 24-mA balanced drive strength, ground-bounce reduction (<0.6 V), flow-through pinout for PCB layout simplification, and SSOP-48 packaging compatible with high-density memory and clock distribution systems.

Technical Context

This device implements four independent 4-bit groups of non-inverting buffers, each with dedicated active-low 3-state enable (OE) inputs enabling flexible 4-, 8-, or full 16-bit bus control. Its edge-rate controlled outputs suppress switching noise and minimize undershoot on transmission lines.

The I_off circuitry ensures outputs remain high-impedance when V_CC = 0 V, preventing backflow current during partial power-down. Input hysteresis (100 mV) improves noise immunity, while bus hold functionality is absent-this variant uses standard TTL-compatible inputs requiring external termination or biasing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC	5 V ±10% - fixed single-supply operation; no dual-rail or adjustable voltage support.
Output Drive	±24 mA - balanced sourcing/sinking enables matched impedance matching on PCB traces without external resistors.
t_PLH/t_PHL	1.5 ns (min) / 4.8 ns (max) - propagation delay suitable for ≤200-MHz bus timing budgets.
V_OL @ 24 mA	≤0.55 V - low output voltage ensures robust LOW-level margin under full load.
V_OH @ –24 mA	≥2.4 V - sufficient HIGH-level margin for TTL and 5-V CMOS interfacing.
I_off	±1 µA at V_CC = 0 V - enables safe hot-insertion and mixed-voltage system partitioning.
Operating Temp	–40°C to +85°C - qualified for industrial-grade embedded and infrastructure applications.

Pinout & Package

74FCT162244ATPVC is housed in a 48-pin SSOP (Shrink Small Outline Package), 300-mil body width, JEDEC MO-118 compliant, with 0.025-inch (0.635-mm) lead pitch and gull-wing leads. Pin 1 marked by notch or dot; pin count verified per TI package drawing DL.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12	Data Inputs (Group 1 A1–A4, A1–A4)	12 total input pins across four 4-bit channels; TTL-compatible VIH/VIL thresholds ensure interoperability with legacy logic.
13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24	Outputs (Group 1 Y1–Y4, Y1–Y4)	12 buffered, 3-state outputs with edge-rate control; low ground bounce (<0.6 V) reduces EMI in dense routing.
25, 26, 33, 34	OE# (1OE#, 2OE#, 3OE#, 4OE#)	Four independent active-low 3-state enables - allows granular bus segmentation (e.g., 4-bit lanes or memory banks).
27, 28, 35, 36, 45, 46, 47, 48	GND / V_CC	Eight power/ground pins (4×GND, 4×V_CC) - distributed supply pins reduce simultaneous switching noise and improve PSRR.
29, 30, 31, 32, 37, 38, 39, 40, 41, 42, 43, 44	Data Inputs & Outputs (Groups 2–4)	Remaining 24 pins complete full 16-bit (4×4) I/O mapping; flow-through layout minimizes trace crossovers on 2-layer boards.

Key Features

Feature	Design Value
Balanced ±24-mA output drivers	Enables direct drive of 50-Ω transmission lines without series termination resistors, reducing BOM count and board area.
Edge-rate control circuitry	Reduces di/dt-induced ground bounce and radiated emissions - measured VOLP <0.6 V at 5 V, 25°C.
I_off partial-power-down support	Prevents damaging back-current when V_CC is unpowered - critical for hot-swap and multi-rail backplane designs.
Flow-through pinout	Input-to-output signal path follows linear left-to-right layout - eliminates layer jumps and vias in compact bus routing.
Industrial temperature range	Validated operation from –40°C to +85°C - suitable for factory automation, telecom line cards, and outdoor infrastructure.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74FCT162244CTPVC	4.1-ns max propagation delay (vs. 4.8 ns); otherwise identical electrical specs and pinout.	Better suited for tighter timing budgets (e.g., >250-MHz bus cycles) where marginal delay reduction is critical.	Select when absolute minimum t_PHL/t_PLH is required and cost premium is acceptable.
74FCT162244ATPACT	TSSOP-48 package (240-mil width, 0.65-mm pitch) vs. SSOP-48 (300-mil, 0.635-mm pitch); same speed grade and drive strength.	Preferred for space-constrained designs using fine-pitch SMT assembly; requires different stencil and reflow profile.	Choose for high-density layouts where board area is constrained and TSSOP handling capability exists.

FAQ

What is the maximum operating frequency supported by the 74FCT162244ATPVC?

The 74FCT162244ATPVC does not specify a maximum clock frequency directly, but its 4.8-ns maximum propagation delay (t_PHL/t_PLH) and 5.6-ns maximum output disable time (t_PLZ) support reliable operation in bus systems with cycle times ≥10 ns - corresponding to effective data rates up to 100 MHz for synchronous interfaces. Signal integrity on PCB traces remains the dominant limiting factor, not internal gate delay.

Does the 74FCT162244ATPVC include bus-hold circuitry on its inputs?

No, the 74FCT162244ATPVC does not feature bus-hold functionality. That capability is exclusive to the CY74FCT162H244T variant. The 74FCT162244ATPVC uses standard TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max) and requires externally biased or terminated inputs to prevent floating states - unlike the H244T, which retains last valid logic state automatically.

Can the 74FCT162244ATPVC be used with 3.3-V logic systems?

The 74FCT162244ATPVC is strictly a 5-V-only device (V_CC = 5 V ±10%). Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) are compatible with 3.3-V CMOS outputs, but its outputs swing rail-to-rail at 5 V and are not 3.3-V tolerant. Direct connection to 3.3-V receivers requires level-shifting or clamping; it must not be powered from 3.3 V.

What is the purpose of the four separate OE# pins on the 74FCT162244ATPVC?

The four active-low output-enable pins (1OE# through 4OE#) correspond to the device's four independent 4-bit buffer sections. This architecture allows selective 3-state control of individual byte lanes - enabling dynamic bus segmentation, power-gated peripheral isolation, or interleaved memory access without disabling the entire 16-bit path. Each OE# drives only its associated Y-group outputs.

Is the 74FCT162244ATPVC RoHS-compliant and lead-free?

Yes, the 74FCT162244ATPVC is RoHS-compliant and lead-free. Per TI's packaging documentation, it carries a "Green (RoHS & no Sb/Br)" eco-plan designation, with CU NIPDAU lead finish and JEDEC Level-1 moisture sensitivity rating - fully compatible with standard Pb-free reflow profiles up to 260°C peak temperature.
