SN74CB3T16210 is a 20-bit FET bus switch from TI that supports 5V and 3.3V voltages and has a 5V-tolerant level shifter.
The SN74CB3T16210 is a high-speed TTL-compatible FET bus switch designed for low-voltage applications. It features a 20-bit capacity organized as two 10-bit bus switches with separate output-enable inputs, allowing for bidirectional data flow between ports when enabled. The device supports mixed-mode signal operation by providing voltage translation that tracks the supply voltage (V CC), facilitating communication between systems using different voltage standards such as 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS.
