Product details
Overview
74ALVT16245DGG,112 from Philips Semiconductors is a 16-bit non-inverting 3-state bidirectional transceiver operating at 2.5V or 3.3V supply with 5V-tolerant I/O pins. It features dual 8-bit A/B ports, direction (DIR) and output enable (OE) controls, bus-hold inputs eliminating external pull-ups, and ±64mA/–32mA drive capability. It is used in high-speed bus interface applications between mixed-voltage subsystems in telecom backplanes and industrial control modules.
For engineers reviewing the 74ALVT16245DGG,112 datasheet, 74ALVT16245DGG,112 pinout, 74ALVT16245DGG,112 application, or 74ALVT16245DGG,112 equivalent, key selection criteria include 3.3V/2.5V VCC compatibility, 5V I/O tolerance, propagation delay ≤2.4ns at 3.3V, bus-hold functionality, and TSSOP-48 package thermal and layout constraints.
Technical Context
The 74ALVT16245DGG,112 implements BiCMOS logic with TTL-compatible input thresholds (VIL = 0.7–0.8V, VIH = 1.7–2.0V) and rail-to-rail output swing under load. Its DIR and OE inputs enable synchronous bidirectional data flow with minimal external timing overhead - OE controls 3-state output enable/disable while DIR selects A→B or B→A directionality.
It supports live insertion/extraction and power-up 3-state behavior, with latch-up protection >500mA per JEDEC Std 17 and ESD robustness >2000V HBM. Bus-hold circuitry maintains stable logic states on unused A/B port pins without external resistors, reducing system component count and board space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3–2.7V or 3.0–3.6V - dual-supply operation enables interoperability across 2.5V and 3.3V logic domains |
| Propagation Delay | 1.5ns typical (tPLH/tPHL, CL = 50pF, VCC = 3.3V) - supports >400MHz bus toggle rates in point-to-point links |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24 | nDIR | Direction control input - low enables A→B data flow; high enables B→A; referenced to VCC/GND |
| 25, 48 | nOE | Active-low output enable - disables all A/B port outputs into high-impedance state when high |
| 2–9, 11–14, 16–17, 19–20, 22–23, 47, 46, 44–43, 41–40, 38–37, 36–35, 33–32, 30–29, 27–26 | nA0–nA7, nB0–nB7 | Bidirectional I/O pins - each pair (e.g., 1A0/1B0) transfers data in selected direction; 5V-tolerant |
| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Eight ground connections - distributed for low-inductance return paths and noise reduction in high-speed switching |
| 7, 18, 31, 42 | VCC | Four power supply pins - decoupling required at each for stable 2.5V/3.3V operation and reduced ground bounce |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC16245DGGR | Lower drive strength (+24mA/–24mA), no bus-hold, operates only at 1.65–3.6V | Suitable for low-power, single-supply 3.3V systems without 5V bus interfacing | Select when 5V tolerance and bus-hold are not required and lower ICCZ is prioritized |
| 74LVT16245MTD | Same 2.5V/3.3V operation and 5V I/O tolerance, but SSOP-48 (SOT370-1) package with wider 7.5mm body | Better thermal dissipation in high-density layouts; requires PCB footprint revision | Select when higher thermal margin is needed and TSSOP-48 mechanical constraints prohibit use |
Compared with SN74ALVC16245DGGR and 74LVT16245MTD, the 74ALVT16245DGG,112 uniquely combines 5V I/O tolerance, integrated bus-hold, and TSSOP-48 compactness - making it optimal for space-constrained, mixed-voltage industrial interfaces where signal integrity and pin count reduction are critical.

FAQ
What supply voltages does the 74ALVT16245DGG,112 support?
The 74ALVT16245DGG,112 operates at two distinct VCC ranges: 2.3–2.7V for 2.5V logic systems and 3.0–3.6V for 3.3V systems. It does not support 5V VCC. Both ranges allow full 5V I/O tolerance, enabling safe interfacing with legacy 5V buses. The 74ALVT16245DGG,112 must be powered within one of these specified windows to guarantee correct logic thresholds, timing, and output drive specifications per the 1998 Philips datasheet.
Does the 74ALVT16245DGG,112 require external pull-up resistors on unused inputs?
No, the 74ALVT16245DGG,112 integrates bus-hold circuitry on all A and B port inputs, providing ±75µA to ±140µA overdrive current to maintain stable logic states without external components. This feature eliminates the need for up to 32 discrete pull-up resistors in typical 16-bit configurations, reducing PCB area, BOM cost, and potential signal integrity issues from unterminated stubs. The 74ALVT16245DGG,112's bus-hold is active across its full operating temperature range (–40°C to +85°C).
What is the maximum propagation delay of the 74ALVT16245DGG,112 at 3.3V operation?
At VCC = 3.3V ±0.3V and CL = 50pF, the maximum propagation delay (tPLH/tPHL) for the 74ALVT16245DGG,112 is 2.4ns over the full operating temperature range (–40°C to +85°C). Typical delay is 1.5ns at Tamb = 25°C. This specification applies to both A→B and B→A data paths and is measured under standard AC test conditions defined in the Philips 1998 datasheet. The 74ALVT16245DGG,112 achieves this performance using BiCMOS process technology optimized for speed and low power.
Can the 74ALVT16245DGG,112 be used in hot-swap applications?
Yes, the 74ALVT16245DGG,112 explicitly supports live insertion and extraction per its Philips datasheet. Its power-up 3-state behavior ensures outputs remain in high-impedance until VCC stabilizes, preventing bus contention during power sequencing. Combined with latch-up immunity exceeding 500mA and ESD protection >2000V HBM, the 74ALVT16245DGG,112 is suitable for modular backplane and field-replaceable unit designs where cards are inserted or removed while the system remains powered.
What package type is used for the 74ALVT16245DGG,112?
The 74ALVT16245DGG,112 uses a 48-pin plastic thin shrink small outline package (TSSOP), designated SOT362-1, with 0.5mm lead pitch and 6.1mm body width. This package is distinct from the SSOP variant (SOT370-1, 7.5mm width) used for the 74ALVT16245DL. The TSSOP-48 footprint enables higher board density and is compatible with standard reflow soldering processes. Thermal resistance and mechanical mounting requirements for the 74ALVT16245DGG,112 are documented in Philips' SOT362-1 package drawings.
