MC74LVX4245

MC74LVX4245 Dual Supply Octal Translating Transceiver with 3−State Outputs The 74LVX4245 is a 24−pin dual−supply, octal translating transceiver that is designed to interface between a 5.0 V bus and a 3.0 V bus in a mixed 3.0 V / 5.0 V supply environment such as laptop computers using a 3.3 V CPU and 5.0 V LCD display. The A port interfaces with the 5V bus; the B port interfaces with the 3.0 V bus. The Transmit/Receive (T/R) input determines the direction of data flow. Transmit (active−High) enables data from the A port to the B port. Receive (active−Low) enables data from the B port to the A port. The Output Enable (OE) input, when High, disables both A and B ports by placing them in 3−State. Features Bi−directional Interface Between 5.0 V and 3.0 V Buses Control Inputs Compatible with TTL Level 5.0 V Data Flow at A Port and 3.0 V Data Flow at B Port Outputs Source/Sink 24 mA at 5.0 V Bus and 12 mA at 3.0 V Bus Guaranteed Simultaneous Switching Noise Level and Dynamic Threshold Performance Available in SOIC and TSSOP Packages Functionally Compatible with the 74 Series 245 NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant VCCB VCCB OE B0 B1 B2 B3 B4 B5 B6 B7 GND 24 23 22 21 20 19 18 17 16 15 14 13 www.onsemi.com 24 1 MARKING DIAGRAMS 24 SOIC−24 DW SUFFIX CASE 751E LVX4245 AWLYYWWG 1 24 24 1...
