Product details
Overview
CALVC164245MDGGREP from Texas Instruments is a 16-bit dual-octal noninverting level-shifting transceiver with independent 2.5 V/3.3 V (VCCA) and 3.3 V/5 V (VCCB) supply rails, enabling bidirectional voltage translation between mixed-voltage buses. It features 3-state outputs, ±24-mA drive strength at 3.3 V, 5.8-ns max propagation delay, and operates across –55°C to 125°C for aerospace and industrial applications.
For engineers reviewing the CALVC164245MDGGREP datasheet, CALVC164245MDGGREP pinout, CALVC164245MDGGREP application, or CALVC164245MDGGREP equivalent, this page delivers verified electrical specs, TSSOP-48 package layout, dual-rail level-shifting behavior, thermal performance data, and validated alternatives for high-reliability system integration.
Technical Context
The CALVC164245MDGGREP implements two independent 8-bit transceiver sections (A↔B), each controlled by dedicated DIR and OE inputs referenced to VCCA. Its dual-supply architecture isolates logic thresholds: control signals track VCCA (2.3–3.6 V), while I/O ports adapt to VCCB (3–5.5 V) on the B side and VCCA on the A side.
It supports four translation modes: 2.5 V ↔ 3.3 V, 3.3 V ↔ 3.3 V, 3.3 V ↔ 5 V, and 2.5 V ↔ 5 V - all with guaranteed VOL ≤ 0.55 V and VOH ≥ 2.0 V under load. Latch-up immunity exceeds 250 mA per JESD17, and power-up sequencing requires VCCA ramp before VCCB to prevent bus contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA Range | 2.3 V to 3.6 V - powers control logic and A-port I/O; defines VIH/VIL thresholds for DIR/OE pins |
| VCCB Range | 3 V to 5.5 V - powers B-port I/O; enables direct interface to 3.3-V or 5-V legacy buses |
| tpd Max | 5.8 ns at VCCA = 3.3 V, VCCB = 5 V - ensures sub-6-ns timing margin for 100-MHz bus cycles |
| IOL/IOH | ±24 mA at VCCA = 3 V - drives standard CMOS loads without external buffers in dense PCB layouts |
| Operating Temp | –55°C to +125°C - qualified per MIL-PRF-38535 Class V for extended-life aerospace and downhole systems |
| Package | TSSOP-48 (DGG) - 12.6 mm × 6.1 mm footprint with 0.5-mm pitch; RoHS-compliant, MSL Level-1 |
| IOZ Leakage | ±10 µA max - maintains high-impedance integrity during sleep mode without pull-up/down conflicts |
Pinout & Package
TSSOP-48 (DGG) package: 12.6 mm × 6.1 mm body, 0.5-mm lead pitch, 1.2-mm max height, gull-wing leads, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (per 8-bit section) | Active-High signal referenced to VCCA; determines data flow direction (A→B or B→A) |
| 1OE, 2OE | Output enable input (per 8-bit section) | Active-Low signal referenced to VCCA; places associated 8-bit port in high-Z state when high |
| 1A1–1A8, 2A1–2A8 | A-side I/O terminals | Bidirectional data lines tied to VCCA rail; accept 2.3–3.6 V logic levels |
| 1B1–1B8, 2B1–2B8 | B-side I/O terminals | Bidirectional data lines tied to VCCB rail; tolerate 3–5.5 V logic levels |
| VCCA, VCCB | Independent supply inputs | VCCA powers control logic and A-port; VCCB powers B-port; no internal connection between supplies |
| GND (Pins 4,7,12,15,20,23,28,31,36,39,44,47) | Ground reference | Twelve dedicated ground pins minimize ground bounce across both 8-bit sections |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail level shifting | Enables interoperability between 2.5-V ASICs and 5-V peripherals without external resistors or translators |
| High drive strength | ±24-mA output current supports fan-out to 10+ CMOS loads at 3.3 V, reducing need for repeaters |
| Low propagation delay | 5.8-ns max tpd allows use in 100-MHz synchronous bus interfaces with timing margin |
| Extended temperature range | –55°C to +125°C operation meets MIL-PRF-38535 Class V requirements for space-grade systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level-shifting transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16T245RHLR | Single 16-bit bus with auto-direction sensing; VCCA/VCCB = 1.2–3.6 V; 3.5-ns tpd; 1.8-V minimum VCCA | Eliminates DIR/OE pins but lacks independent dual-section control; unsuitable for asymmetric bidirectional protocols | Select when direction is data-driven and lowest latency is critical; not drop-in for existing CALVC164245MDGGREP layouts |

FAQ
What is the maximum operating temperature for CALVC164245MDGGREP?
CALVC164245MDGGREP is rated for continuous operation from –55°C to +125°C ambient temperature, meeting MIL-PRF-38535 Class V qualification standards. This extended range enables deployment in downhole oil/gas sensors, satellite payload electronics, and engine-control modules where thermal extremes are routine. The device's thermal resistance (θJA = 70°C/W) and 10-year life projection at 105°C junction temperature further validate its suitability for harsh-environment applications.
Does CALVC164245MDGGREP support 2.5-V to 5-V bidirectional translation?
Yes, CALVC164245MDGGREP explicitly supports 2.5-V to 5-V bidirectional translation: VCCA operates from 2.3 V to 3.6 V (covering 2.5 V nominal), and VCCB supports 3 V to 5.5 V (covering 5 V nominal). Electrical characteristics tables confirm VOH ≥ 2.0 V and VOL ≤ 0.55 V under 2.5-V A-side and 5-V B-side conditions, with full functionality across the entire recommended operating range - no derating or external circuitry required.
How many ground pins does CALVC164245MDGGREP have in the TSSOP-48 package?
CALVC164245MDGGREP has twelve dedicated ground pins (Pins 4, 7, 12, 15, 20, 23, 28, 31, 36, 39, 44, and 47) in its TSSOP-48 (DGG) package. This distributed grounding scheme minimizes simultaneous switching noise and ground bounce across both 8-bit sections, directly supporting signal integrity in high-speed 100-MHz bus environments - a key differentiator versus generic 16-bit translators with fewer GND connections.
Can CALVC164245MDGGREP be used with VCCA = 2.5 V and VCCB = 3.3 V?
Yes, CALVC164245MDGGREP is fully specified for VCCA = 2.5 V and VCCB = 3.3 V operation. The datasheet's Electrical Characteristics tables include test conditions at VCCA = 2.3–2.7 V and VCCB = 3–3.6 V, with measured VOH ≥ 1.7 V and VOL ≤ 0.6 V under 12-mA load. Propagation delay remains ≤ 7.6 ns, confirming reliable timing closure in FPGA-to-ASIC interconnects and other 2.5-V/3.3-V mixed-signal interfaces.
Is CALVC164245MDGGREP pin-compatible with commercial-grade SN74ALVC164245 variants?
CALVC164245MDGGREP shares identical pinout and package (TSSOP-48 DGG) with commercial SN74ALVC164245 variants such as CALVC164245IDGGREP, but is not a drop-in replacement due to its enhanced screening: it undergoes extended temperature burn-in, radiation hardness assurance, and MIL-PRF-38535 Class V qualification. Board layout is compatible, but system-level validation must account for differences in parametric limits and lifetime reliability models.
