Product details

Overview

74ACT16244DGGR-NG from Texas Instruments is a 16-bit non-inverting buffer/line driver with 3-state outputs, designed for memory address driving, bus interfacing, and clock distribution in industrial digital systems. It operates at 4.5–5.5 V, delivers ±24 mA output drive, supports TTL-compatible inputs, and features flow-through pinout for optimized PCB layout.

For engineers reviewing the 74ACT16244DGGR-NG datasheet, 74ACT16244DGGR-NG pinout, 74ACT16244DGGR-NG application, or 74ACT16244DGGR-NG equivalent, key selection criteria include its 48-pin TSSOP (DGG) package, -40°C to +85°C temperature range, 3-state enable control per 4-bit group, and EPIC™ CMOS process enabling 500-mA latch-up immunity.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low output-enable (OE) control. Its flow-through architecture places inputs on one side and outputs on the opposite side of the 48-pin TSSOP package, minimizing trace crossovers and signal skew.

Distributed V_CC and GND pins reduce high-speed switching noise, while the EPIC™ 1-μm CMOS process ensures TTL-voltage compatibility (V_IL = 0.8 V, V_IH = 2 V) and robust 500-mA latch-up immunity at 125°C - critical for stable operation in noisy industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with standard 5-V logic rails and tolerance against supply ripple.
Output Drive	±24 mA - sufficient to drive multiple TTL loads or terminate short PCB traces without external buffering.
Propagation Delay	3.4 ns to 8.7 ns (t_PHL/t_PLH) - enables reliable operation in high-speed address/data buses up to ~100 MHz.
3-State Enable Time	t_PZH = 3 ns min, t_PHZ = 5.4 ns min - supports fast bus arbitration and dynamic bus sharing.
Input Compatibility	TTL-level (V_IL ≤ 0.8 V, V_IH ≥ 2 V) - allows direct interfacing with legacy 74LS/74F logic without level shifters.
Operating Temperature	-40°C to +85°C - qualified for industrial-grade embedded control and instrumentation applications.
Power Dissipation	0.85 W max (T_A = 55°C, DGG package) - manageable thermal profile with standard PCB copper pour.

Pinout & Package

74ACT16244DGGR-NG is housed in a 48-pin Thin Shrink Small-Outline Package (TSSOP, DGG), 12.6 mm × 6.2 mm × 1.2 mm, with 0.5-mm pitch and Q1 pin-1 quadrant orientation. The package supports fine-pitch automated assembly and provides low-inductance power/ground distribution via multiple V_CC and GND pins.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE	Active-low output-enable inputs	Independent control per 4-bit section - enables flexible bus segmentation and partial 3-state management.
1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4	Buffer inputs	True (non-inverting) inputs arranged for flow-through routing - simplifies layer stacking and reduces vias.
1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4	Buffer outputs	3-state outputs with symmetrical drive - supports bidirectional bus loading when paired with complementary drivers.
V_CC (Pins 7, 14, 21, 28, 35, 42)	Power supply	Six distributed V_CC pins minimize IR drop and high-frequency impedance - critical for clean switching in dense logic arrays.
GND (Pins 4, 11, 18, 25, 32, 39)	Ground reference	Six dedicated ground pins provide low-inductance return paths - suppresses simultaneous switching noise (SSN).

Key Features

Feature	Design Value
Flow-through architecture	Input and output pins placed on opposite sides of package - eliminates crossing traces and reduces signal path length by up to 40%.
Distributed V_CC/GND	6 V_CC and 6 GND pins interleaved across package - lowers power delivery impedance and improves EMI performance.
EPIC™ CMOS process	1-μm implanted CMOS technology - delivers TTL compatibility, 500-mA latch-up immunity, and stable timing over full temperature range.
3-state output symmetry	Matched t_PLZ/t_PZL and t_PHZ/t_PZH delays - ensures deterministic bus release timing during multi-driver contention.
TTL-input compatibility	Guaranteed V_IH = 2 V, V_IL = 0.8 V - interoperates directly with 74LS, 74F, and microcontroller GPIOs without level translation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ACT16244DGGR	Same die, identical electrical specs, RoHS-compliant NIPDAU finish; differs only in part marking and packaging documentation.	No functional difference - fully interchangeable in design and qualification.	Select SN74ACT16244DGGR for new designs requiring TI's current production part number and full RoHS compliance documentation.
74ACT16244DLR	Same logic function but in 48-pin SSOP (DL) package - 0.65-mm pitch vs. DGG's 0.5-mm pitch; higher thermal resistance (1.2 W vs. 0.85 W).	Preferred where board assembly uses SSOP-compatible pick-and-place or requires slightly higher standoff height.	Choose 74ACT16244DLR if existing tooling or reliability testing is based on SSOP footprint and thermal mass requirements allow.

Compared with SN74ACT16244DGGR and 74ACT16244DLR, the 74ACT16244DGGR-NG offers identical core functionality but with legacy part-numbering and potentially different tape-and-reel labeling; it remains suitable for industrial replacement and continuity programs where DGG-package density and thermal performance are prioritized.
