Nexperia USA Inc. CBTD16210DGG,518

Overview

CBTD16210DGG,518 from NXP Semiconductors (formerly Philips) is a 20-bit TTL-compatible bus switch with dual 10-bit output-enable control, designed for bidirectional 5.5 V ↔ 3.3 V level shifting in high-speed data buses. It features 5 Ω typical on-state resistance, 250 ps propagation delay (CL = 50 pF), and operates across –40°C to +85°C. Used in legacy industrial backplanes and mixed-voltage memory expansion interfaces.

For engineers reviewing the CBTD16210DGG,518 datasheet, CBTD16210DGG,518 pinout, CBTD16210DGG,518 application, or CBTD16210DGG,518 equivalent, key selection criteria include verified 5 V-to-3.3 V level-shifting capability, dual independent OE control for partitioned bus management, low capacitive loading (CIN = 4.3 pF, COUT = 6.9 pF), and TSSOP-48 package compatibility with high-density PCB layouts.

Technical Context

The CBTD16210 implements two independent 10-bit transmission-gate-based bus switches, each with dedicated OE input enabling precise timing control of signal routing. Its integrated diode-to-VCC architecture allows safe clamping during 5 V input transitions while delivering 3.3 V–compatible outputs without external components.

It operates under strict DC supply constraints (VCC = 4.5–5.5 V), supports TTL-level control inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and maintains high-impedance isolation (ICCZ = 4.0 µA) when disabled-critical for hot-swap and power-gated subsystems in embedded controllers.

FAQ

Is CBTD16210DGG,518 compatible with 5 V microcontroller GPIO driving 3.3 V FPGA I/O banks?

Yes. The device's integrated VCC-clamp diode and 5 Ω Ron allow direct 5 V input to 3.3 V output translation without external components. It meets VIH ≥ 2.0 V and VIL ≤ 0.8 V thresholds for TTL compatibility and supports 4.5–5.5 V VCC operation-ensuring robust signal transfer across this voltage boundary under all specified temperature conditions.

What is the maximum data rate supported by CBTD16210DGG,518 in a parallel bus configuration?

Based on its 250 ps propagation delay (tPD) and 6.9 pF output capacitance, CBTD16210DGG,518 supports reliable operation up to 1 Gbps aggregate throughput in short-run (<10 cm), low-noise parallel buses. Real-world validation shows clean eye diagrams at 100 MHz clock rates with 10-bit wide data paths, assuming proper termination and ground plane design.

Can both 10-bit sections be used simultaneously as a single 20-bit switch?

Yes. When both 1OE and 2OE are driven low, the device functions as a unified 20-bit bus switch with continuous A-to-B connectivity. The pinout groups 1A1–1A10/1B1–1B10 and 2A1–2A10/2B1–2B10 are electrically isolated but share the same VCC and GND rails-enabling synchronized or independent control per design requirements.

Does CBTD16210DGG,518 require external pull-up or pull-down resistors on OE pins?

No. The OE inputs are TTL-compatible with defined VIH (≥2.0 V) and VIL (≤0.8 V) thresholds and exhibit ±1 µA leakage current. They may be driven directly from microcontroller GPIO or 74-series logic outputs. External resistors are unnecessary unless specific noise immunity or power-down default states are required by system architecture.
