Product details
Overview
CLVTH16652IDGGREP from Texas Instruments is a 16-bit dual-supply bus transceiver with real-time/stored data selection, 3.3-V VCC operation, 5-V tolerant inputs/outputs, and hot-insertion support via Ioff and power-up 3-state. It functions as two independent 8-bit transceivers or one 16-bit unit in mixed-voltage backplane or memory interface applications.
For engineers reviewing the CLVTH16652IDGGREP datasheet, CLVTH16652IDGGREP pinout, CLVTH16652IDGGREP application, or CLVTH16652IDGGREP equivalent, key selection criteria include its 2.7–3.6-V supply range, bus-hold on all data inputs, distributed VCC/GND pins for noise reduction, and support for simultaneous A↔B bidirectional transfer with stored-data arbitration.
Technical Context
This device implements dual 8-bit D-type flip-flop registers per bus (A and B), each controlled by dedicated clock (CLKAB/CLKBA), select (SAB/SBA), and output-enable (OEAB/OEBA) inputs. Real-time transfer occurs when SAB/SBA = L; stored-data transfer requires SAB/SBA = H and valid clock edges.
Its ABT BiCMOS process enables TTL-level compatibility at 3.3-V VCC, with guaranteed 5-V input tolerance, <0.8-V output ground bounce (VOLP), and latch-up immunity >500 mA per JESD 17. Bus-hold circuitry eliminates external pull resistors on all 32 data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V without functional degradation |
| Input Voltage Tolerance | −0.5 V to 7 V - enables direct interfacing with 5-V logic without level shifters |
| Max Clock Frequency | 150 MHz - ensures high-speed bus arbitration in DDR memory buffers and telecom backplanes |
| Ioff Current | ±100 µA at VCC = 0 V - prevents backflow current during hot insertion or partial power-down |
| Bus-Hold Current | ±500 µA at VCC = 3.6 V - actively maintains valid logic state on floating A/B port inputs |
| tPLH/tPHL (CLK→Data) | 1.3–4.7 ns - guarantees sub-5-ns propagation for timing-critical synchronous bus control |
| Output Drive (IOL) | 64 mA - drives standard TTL loads and stubs in multi-drop bus topologies |
Pinout & Package
CLVTH16652IDGGREP uses a 56-pin Thin Shrink Small-Outline Package (TSSOP-DGG), 12.5 mm × 6.1 mm body, 0.5-mm pitch, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OEAB, 2OEAB, 1OEBA, 2OEBA | Output Enable (active low) | Independently controls 8-bit A→B and B→A output drivers; enables isolation or bidirectional flow |
| 1CLKAB, 2CLKAB, 1CLKBA, 2CLKBA | Register Clock (rising-edge triggered) | Latches A or B bus data into internal D flip-flops on each low-to-high transition |
| 1SAB, 2SAB, 1SBA, 2SBA | Select Control (high = stored data) | Determines whether outputs reflect real-time bus values (S = L) or registered data (S = H) |
| A1–A8, B1–B8 (×2 groups) | Bidirectional Data I/O | 32 total data terminals with bus-hold; no external pull resistors required for unused lines |
| VCC, GND (×8 each) | Power Distribution | Distributed VCC/GND pins minimize simultaneous switching noise across high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Hot-insertion support | Ioff and power-up 3-state prevent damage and bus contention during live board insertion |
| Mixed-mode signal operation | 3.3-V VCC with 5-V-tolerant I/O allows seamless integration between legacy 5-V and modern 3.3-V subsystems |
| Flow-through architecture | Input and output pins positioned on opposite sides of package to simplify PCB trace routing and reduce crosstalk |
| Real-time/stored arbitration | Select-control logic eliminates multiplexer glitches during mode transitions between live and latched data paths |
| Low static power dissipation | 0.19 mA typical ICC in disabled state - reduces system standby power in always-on infrastructure equipment |

FAQ
What is the operating temperature range for CLVTH16652IDGGREP?
The CLVTH16652IDGGREP is rated for −40°C to +85°C operation, meeting industrial temperature requirements. This range is validated per JEDEC standards including temperature cycling and biased 85/85 testing, and is explicitly specified in TI's ordering information and qualification pedigree documentation for this part number.
Does CLVTH16652IDGGREP support true 5-V input compatibility?
Yes, CLVTH16652IDGGREP supports input voltages up to 7 V (absolute max) and is fully specified for 5-V TTL-level inputs while operating at 3.3-V VCC. Its input structure tolerates 5-V signals without clamping diodes or external resistors, enabling direct connection to legacy 5-V logic families.
How does the bus-hold feature work on CLVTH16652IDGGREP?
The CLVTH16652IDGGREP integrates active bus-hold circuitry on all 32 A/B port data inputs. When an input floats, the internal circuit applies ±500 µA hold current to maintain the last-valid logic state, eliminating the need for external pullup/pulldown resistors and preventing undefined states in unterminated stubs or disconnected modules.
Can CLVTH16652IDGGREP be used for hot-insertion applications?
Yes, CLVTH16652IDGGREP is explicitly designed for hot insertion with dual protection: Ioff circuitry disables outputs and blocks reverse current when VCC = 0 V, and power-up 3-state holds all outputs in high-impedance until VCC stabilizes above 1.5 V-both confirmed in the SCBS787 datasheet functional description and absolute ratings table.
What package type and dimensions does CLVTH16652IDGGREP use?
CLVTH16652IDGGREP uses a 56-pin Thin Shrink Small-Outline Package (TSSOP-DGG) with 0.5-mm pitch, 12.5 mm × 6.1 mm body size, and 1.2-mm maximum height. Its pinout and mechanical drawing are documented in TI's DGG package specification and verified in the SCBS787 datasheet top-view diagram.
