LVC4245A - ETC

LVC4245A 74LVC4245A / SN74LVC4245A

This 8-bit (octal) noninverting bus transceiver contains two separate supply rails; B port has VCCB, which is set at 3.3 V, and A port has VCCA, which is set at 5 V. This allows for translation from a 3.3-V to a 5-V environment, and vice versa. (5 V) VCCA DIR A1 A2 A3 A4 A5 A6 A7 A8 GND GND 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 V.

Features

rom the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. The SN74LVC4245A pinout allows the designer to switch to a normal all-3.3-V or all-5-V 20-pin ’245 device without board re-layout. The designer uses the data paths for pins 2
  –11 and 14
  –23 of the SN74LVC4245A to align with the conventional ’245 pinout. The SN74LVC4245A is characterized for operation from
  –40°C to 85°C. FUNCTION TABLE INPUTS OE L L H DIR L H X OPERATION.
