Description

SN74CBTD3384DBQR is an 8-bit bidirectional bus transceiver/level shifter from TI’s CBTD family. It connects two 8-bit buses (A and B) and lets data move in either direction under control of a single DIR input. An enable (OE) tri-states the outputs, allowing bus isolation. The device provides independent supply rails on the two sides (VCCA and VCCB), enabling voltage level translation between disparate logic families. Key features typically include Ioff (power-off isolation), TTL/CMOS-compatible inputs, and 3-state outputs for high-density bus interfacing. Applications include interfacing devices with different logic levels, buffering backplanes, or connecting microcontrollers to peripherals where bidirectional data paths and level shifting are needed. The DBQR suffix denotes the packaging/tape-and-reel variant of the part. For exact electrical specs, timing, and pinout, consult the TI datasheet.

Features

Here are the typical features of the SN74CBTD3384DBQR (bus transceiver/buffer):
- Octal (8-bit) bidirectional buffer/driver with a single bidirectional data path
- Direction control input (DIR) determines A→B or B→A data flow
- Separate Output Enable (OE) to put outputs in high-impedance
- Noninverting data path with 3-state outputs on both sides
- TTL/CMOS input thresholds; suitable for interfacing different voltage domains
- ESD protection on inputs and outputs
- Fast switching suitable for bus interfacing; low static power
- Package: DBQR (compact surface-mount package)
Note: For exact electrical specs (voltage ranges, propagation delays, power, temperature range) refer to the TI datasheet.

Package

RoHS-compliant DBQ small-outline package (gull-wing leaded, SOP/TSSOP-family; typically 20 pins for this device).

Pinout

- Pin count: 20 pins (20-pin package)
- Function: Octal buffer/driver with 3-state outputs (8-bit bus buffer with enable), used to buffer and isolate an 8-bit data bus.
