Product details
Overview
74FCT162244ATPVCG4 from Texas Instruments is a 16-bit non-inverting 3-state buffer/line driver with balanced 24-mA output drivers, designed for high-speed bus interface applications including memory and clock distribution. It operates at 5V ±10%, supports –40°C to +85°C industrial temperature range, features Ioff partial-power-down protection, and delivers typical output skew <250 ps.
For engineers reviewing the 74FCT162244ATPVCG4 datasheet, 74FCT162244ATPVCG4 pinout, 74FCT162244ATPVCG4 application, or 74FCT162244ATPVCG4 equivalent, key selection criteria include its 24-mA balanced drive strength, ground bounce <0.6V, propagation delay ≤4.8 ns, and SSOP-48 package compatibility with legacy 300-mil footprint designs.
Technical Context
This device implements four independent 4-bit groups of non-inverting buffers, each controlled by dedicated active-low 3-state enable inputs (1OE–4OE). Its flow-through pinout minimizes trace routing complexity on dense PCBs.
The internal output drivers integrate current-limiting resistors to reduce system switching noise and eliminate need for external termination on transmission lines. Ioff circuitry ensures outputs remain high-impedance during power-down, preventing backflow current when VCC = 0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - Compatible with standard TTL/CMOS logic rails; no level-shifting required in 5-V systems. |
| Output Drive | ±24 mA - Balanced sink/source capability enables clean driving of moderate-capacitance buses without overshoot or excessive ground bounce. |
| Propagation Delay | ≤4.8 ns - Ensures timing integrity in high-speed address/data paths up to ~200 MHz clock domains. |
| Output Skew | <250 ps - Critical for simultaneous multi-bit signal integrity in parallel bus applications like memory interfaces. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - Reduces noise coupling into adjacent signals and power rails during switching. |
| Ioff Protection | Enabled - Allows safe operation in partial-power-down systems; prevents damaging current flow when VCC = 0V. |
| ESD Rating | >2000 V HBM - Provides robust handling margin during board assembly and field service. |

FAQ
What is the operating voltage range for the 74FCT162244ATPVCG4?
The 74FCT162244ATPVCG4 operates at VCC = 5V ±10%, meaning it is fully specified from 4.5 V to 5.5 V. This range ensures compatibility with standard TTL logic families and eliminates need for voltage regulation in most 5-V systems. Operation outside this range may impair functionality or reliability, and is not guaranteed by Texas Instruments' specifications.
Does the 74FCT162244ATPVCG4 support partial-power-down mode?
Yes, the 74FCT162244ATPVCG4 includes Ioff circuitry that disables outputs when VCC = 0V, preventing damaging current backflow during partial-power-down conditions. This feature is validated per datasheet Section "Functional Description" and enables safe use in hot-swap or modular power architectures where subsystems power up/down independently.
What is the maximum propagation delay of the 74FCT162244ATPVCG4?
The maximum propagation delay (tPLH/tPHL) for the 74FCT162244ATPVCG4 is 4.8 ns over the full industrial temperature range (–40°C to +85°C) and VCC = 4.5 V to 5.5 V. This value is confirmed in the "Switching Characteristics" table of the official Texas Instruments datasheet (Document #: 38-00396-C), and applies to all 16 channels under worst-case conditions.
Is the 74FCT162244ATPVCG4 pin-compatible with other variants in the FCT162xx4 family?
Yes, the 74FCT162244ATPVCG4 shares identical pinout and package (SSOP-48) with CY74FCT16244ATPVC and 74FCT162244CTPVCT. However, functional differences exist: the 74FCT162244ATPVCG4 lacks bus-hold inputs (unlike CY74FCT162H244T) and uses balanced 24-mA drivers (vs. asymmetric 32/64-mA in CY74FCT16244T), so electrical substitution requires verification of drive and noise requirements.
What package type does the 74FCT162244ATPVCG4 use, and what are its key mechanical features?
The 74FCT162244ATPVCG4 uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 25-mil lead pitch (package code O48). Key mechanical features include dual VCC (pins 24, 48) and dual GND (pins 25, 47) terminals for improved power integrity, and JEDEC MO-153 compliance. Its 1.2-mm max height and gull-wing leads support standard SMT reflow profiles.
