Nexperia USA Inc. CBTD16211DGG,118

Overview

CBTD16211DGG,118 from NXP Semiconductors (formerly Philips) is a 24-bit TTL-compatible bus exchange switch with dual 12-bit configurable topology, 5 Ω on-state resistance, integrated 5 V-to-3.3 V level shifting diode, and independent OE control per 12-bit bank. It operates from –40 °C to +85 °C and enables high-speed bidirectional data routing in mixed-voltage memory and peripheral interconnects.

For engineers reviewing the CBTD16211DGG,118 datasheet, CBTD16211DGG,118 pinout, CBTD16211DGG,118 application, or CBTD16211DGG,118 equivalent, key selection criteria include propagation delay (0.25 ns), output-enable timing (1.5–8.5 ns), on-resistance tolerance (5–7 Ω), input/output capacitance (4.3 pF / 6.9 pF), and TSSOP-56 thermal performance under 5.5 V supply.

Technical Context

The CBTD16211DGG,118 implements two independent 12-bit analog bus switches with TTL-level control inputs and integrated clamping diodes for level translation between 5 V and 3.3 V domains. Its architecture supports three operational modes: dual 12-bit switching, single 20-bit configuration, or split 10-bit usage - all governed by separate 1OE and 2OE signals.

Each switch channel exhibits low on-resistance (5–7 Ω at VCC = 4.5 V), minimal propagation delay (0.25 ns typical), and high off-isolation (CI(OFF) = 8 pF). The device uses complementary MOSFET pairs per switch path and integrates ESD protection exceeding 1000 V CDM per JESD22-C101.

FAQ

What is the maximum operating frequency supported by CBTD16211DGG,118?

The CBTD16211DGG,118 does not specify a maximum clock frequency, but its 0.25 ns typical propagation delay and 6.9 pF output capacitance support signal edges with <1 ns rise/fall times. In practice, it reliably handles DDR1/DDR2 address/control buses up to 200 MHz with proper layout and termination.

Can CBTD16211DGG,118 be used for unidirectional signal translation only?

Yes - although bidirectional by design, the CBTD16211DGG,118 can operate unidirectionally by connecting inputs only to A-side pins and using B-side pins exclusively as outputs. Its symmetric Ron (5–7 Ω) and matched capacitance ensure equal performance in either direction without modification.

Is external pull-up or pull-down required on OE pins?

No - the 1OE and 2OE inputs are TTL-compatible with defined VIH (≥2.0 V) and VIL (≤0.8 V) thresholds. When driven directly from CMOS or TTL logic outputs, no external biasing is needed. Floating OE pins are undefined and must be avoided.

Does CBTD16211DGG,118 support hot-swap or live-insertion?

No - the CBTD16211DGG,118 lacks powered-off protection or Ioff specification. Applying voltage to A/B pins while VCC is absent may forward-bias internal diodes and cause excessive current. Power sequencing (VCC before signals) is mandatory per Absolute Maximum Ratings.
