Product details
Overview
SN74LVC16245AGQLR from Texas Instruments is a 16-bit dual-octal noninverting bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between 1.65–3.6 V buses. It supports mixed-mode signaling (5.5 V-tolerant inputs at 3.3 V VCC), delivers ≤4 ns propagation delay at 3.3 V, and enables isolation via independent 1OE/2OE controls - used in printer peripheral interfaces and industrial backplane interconnects.
For engineers reviewing the SN74LVC16245AGQLR datasheet, SN74LVC16245AGQLR pinout, SN74LVC16245AGQLR application, or SN74LVC16245AGQLR equivalent, key selection criteria include 5.5 V input tolerance, Ioff-enabled live insertion support, dual 8-bit directional control, and guaranteed tpd ≤5.0 ns across –40°C to 125°C.
Technical Context
The SN74LVC16245AGQLR implements two independent 8-bit transceiver channels (A↔B), each with dedicated DIR and OE pins enabling simultaneous or staggered direction control. Its CMOS design features rail-to-rail output swing, balanced drive strength (±24 mA at 3.0 V), and input thresholds scaled to VCC (VIH = 2.0 V min at VCC = 3.0 V).
It supports partial-power-down operation via Ioff circuitry that disables outputs and blocks current flow when VCC = 0 V, while maintaining 5.5 V tolerance on all I/O pins regardless of supply state. The device operates across –40°C to 125°C with thermal resistance RθJA = 67.1°C/W (DGG package) and meets JESD22-A114 (2000 V HBM) ESD requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V legacy peripherals in mixed-voltage systems. |
| Max Propagation Delay | 5.0 ns at VCC = 3.3 V, TA = 125°C - Ensures timing closure in high-speed 16-bit parallel bus applications. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sustains signal integrity driving 50 Ω transmission lines or multiple CMOS loads. |
| Ioff Current | ±10 µA max at VI/VO = 5.5 V, VCC = 0 V - Prevents back-drive damage during hot-swap or power sequencing. |
| Operating Temperature | –40°C to +125°C - Qualified for industrial and extended-temperature embedded control environments. |
| ESD Rating | 2000 V HBM, 1000 V CDM - Meets JEDEC standards for robust handling in automated assembly. |
Pinout & Package
SN74LVC16245AGQLR uses a 56-ball GQL (micro BGA) package measuring 7.0 mm × 4.5 mm × 0.9 mm, optimized for space-constrained PCB layouts in portable and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH logic selects A→B (H) or B→A (L) data flow per channel; enables independent bus arbitration. |
| 1OE, 2OE | Output enable input | Active-LOW assertion places corresponding 8-bit port in high-impedance state, isolating buses without external switches. |
| 1A1–1A8, 2A1–2A8 | Port A I/O terminals | Bi-directional data lines tied to local controller or microprocessor bus; tolerate 5.5 V regardless of VCC. |
| 1B1–1B8, 2B1–2B8 | Port B I/O terminals | Bi-directional data lines connected to peripheral, memory, or secondary processor bus; fully 3.3 V compatible. |
| VCC | Power supply | Single 1.65–3.6 V supply powers both transceiver sections; requires local 0.1 µF bypass capacitor per VCC pin. |
| GND | Ground reference | Eight dedicated ground balls minimize ground bounce; must be connected to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode voltage translation | 5.5 V-tolerant inputs operate reliably with 1.65–3.6 V VCC - eliminates external level shifters in 3.3 V ↔ 5 V interfacing. |
| Ioff partial-power-down protection | Blocks current flow when VCC = 0 V - enables safe live insertion into powered-backplane systems. |
| Dual independent channel control | Separate DIR/OE pins per 8-bit section allow asymmetric bus management (e.g., A→B on Channel 1, B→A on Channel 2). |
| Low ground bounce (VOLP) | <0.8 V typical at VCC = 3.3 V, TA = 25°C - maintains noise margin in high-speed switching with light capacitive loads. |
| High noise immunity | VIH/VIL thresholds scale with VCC (e.g., VIH = 2.0 V min at VCC = 3.0 V) - ensures reliable logic detection across voltage range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245ADGGR | TSSOP-48 package (12.5 × 6.1 mm); higher RθJA (67.1°C/W); leaded finish. | Suitable for prototyping and manual soldering; less compact than GQL for wearables or dense RF modules. | Select when board assembly uses standard reflow profiles and space constraints are moderate. |
| SN74AVC16245DGGR | Lower VCC range (1.2–3.6 V); faster tpd (≤2.8 ns at 3.3 V); no 5.5 V input tolerance. | Better for 1.2 V/1.5 V core logic but incompatible with 5 V peripherals without external clamping. | Choose only if system operates exclusively below 3.6 V and requires sub-3 ns timing - not a drop-in replacement. |
Compared with SN74LVC16245AGQLR, SN74LVC16245ADGGR offers easier handling and test access but increases PCB area by 3.4×; SN74AVC16245DGGR improves speed and low-voltage operation but sacrifices 5 V interoperability - making SN74LVC16245AGQLR optimal for compact, mixed-voltage industrial designs requiring field-proven robustness.

FAQ
What is the maximum operating temperature for SN74LVC16245AGQLR?
The SN74LVC16245AGQLR is rated for continuous operation from –40°C to +125°C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life tests. This rating applies to the GQL package under natural convection conditions with proper PCB copper pour and thermal vias.
Does SN74LVC16245AGQLR support 5 V inputs when powered at 1.8 V?
Yes, SN74LVC16245AGQLR accepts input voltages up to 5.5 V regardless of VCC level (1.65–3.6 V). At VCC = 1.8 V, inputs remain fully 5 V tolerant - enabling direct connection to legacy 5 V peripherals without external clamping diodes or level shifters.
How does the Ioff feature function in SN74LVC16245AGQLR during power-down?
When VCC = 0 V, the Ioff circuitry in SN74LVC16245AGQLR actively disables all output drivers and isolates input/output terminals, limiting leakage current to ±10 µA maximum even with 5.5 V applied to any pin - preventing back-drive damage during hot-swap or partial system power-down sequences.
What is the recommended bypass capacitor configuration for SN74LVC16245AGQLR?
TI recommends placing a 0.1 µF ceramic capacitor between each VCC pin and the nearest ground ball on the PCB. For the GQL package with four VCC connections, use four discrete 0.1 µF capacitors placed within 2 mm of their respective VCC pads, with low-inductance vias to an internal ground plane.
Can SN74LVC16245AGQLR be used as a single 16-bit transceiver instead of two 8-bit units?
Yes, SN74LVC16245AGQLR can operate as one unified 16-bit transceiver by tying 1DIR = 2DIR and 1OE = 2OE. Its internal architecture guarantees matched propagation delay (tsk(o) ≤1.5 ns) and simultaneous enable/disable across all 16 bits - critical for coherent data word transfer in memory-mapped I/O systems.
