The low on-state resistance of the switches allows connections to be made without adding propagation delay. A diode to VCC is integrated on the die to allow for level shifting between 5-V inputs and 3.3-V outputs. 1 24 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 12 13 VCC 2B5 2A5 2A4 2B4 2B3 2A3 2A2 2B2 2B1 2A1 2OE 1A1 1B1 1OE NC V CC SN54CBTD3384 . . . FK PACKAGE (TOP VIEW) These devices are organized as two 5-bit switches with separate output-enable (OE) inputs. When OE is low, the switch is on and port A is connected to port B. When OE is high, the switch is open and a high-impedance state exists between the two ports. 1A2 1B2 1B3 NC 1A3 1A4 1B4 4 3 2 1 28 27 26 25 6 24 7 23 8 22 9 21 10 20 11 19 12 13 14 15 16 17 18 2A4 2B4 2B3 NC 2A3 2A2 2B2 1B5 1A5 GND NC 2OE 2A1 2B1 The SN54CBTD3384 is characterized for operation over the full military temperature range from -55C to 125C.
