DESCRIPTION:

The FCT164245T 16-bit 3.3V-to-5V translator is built using advanced dual metal CMOS technology. This high-speed, low-power transceiver is designed to interface between a 3.3V bus and a 5V bus in a mixed 3.3V/5V supply environment. This enables system designers to interface TTL compatible 3.3V components with 5V components. The direction and output enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver. The A port interfaces with the 3.3V bus; the B port interfaces with the 5V bus. The direction control (xDIR) pin controls the direction of data flow. The output enable pin (xOE) overrides the direction control and disables both ports. These control signals can be driven from either 3.3V or 5V devices.

FEATURES:

• 0.5 MICRON CMOS Technology

• Bidirectional interface between 3.3V and 5V buses

• Control inputs can be driven from either 3.3V or 5V circuits

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0)

• VCC1 = 5V ±10, VCC2 = 2.7V to 3.6V

• High drive outputs (-32mA IOH, 64mA IOL) on 5V port

• Power off disable on both ports permits “live insertion”

• Typical VOLP (Output Ground Bounce) < 0.9V at VCC1 = 5V, VCC2 = 3.3V, TA = 25°C

• Available in SSOP and TSSOP packages
