MC74LVX4245 Dual Supply Octal Translating Transceiver with 3State Outputs The 74LVX4245 is a 24pin dualsupply, octal translating www.onsemi.com 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 MARKING computers using a 3.3 V CPU and 5.0 V LCD display. The A port DIAGRAMS 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 24 flow. Transmit (activeHigh) enables data from the A port to the B 24 SOIC24 port. Receive (activeLow) enables data from the B port to the A port. LVX4245 DW SUFFIX The Output Enable (OE) input, when High, disables both A and B AWLYYWWG CASE 751E 1 ports by placing them in 3State. 1 Features Bidirectional Interface Between 5.0 V and 3.0 V Buses 24 Control Inputs Compatible with TTL Level LVX 24 TSSOP24 5.0 V Data Flow at A Port and 3.0 V Data Flow at B Port 4245G DT SUFFIX ALYW Outputs Source/Sink 24 mA at 5.0 V Bus and 12 mA at 3.0 V Bus CASE 948H 1 Guaranteed Simultaneous Switching Noise Level and Dynamic 1 Threshold Performance Available in SOIC and TSSOP Packages LVX4245 = Specific Device Code A = Assembly Location Functionally Compatible with the 74 Series 245 WL, L = Wafer Lot NLV Prefix for Automotive and Other Applications Requiring Y = Year Unique Site and Control Change Requirements AECQ100 WW, W = Work Week Qualified and PPAP Capable G or = PbFree Package These Devices are PbFree, Halogen Free/BFR Free and are RoHS (Note: Microdot may be in either location) Compliant PIN NAMES Pins Function V V OE B0 B1 B2 B3 B4 B5 B6 B7 GND CCB CCB OE Output Enable Input 24 23 22 21 20 19 18 17 16 15 14 13 T/R Transmit/Receive Input A0A7 Side A 3State Inputs or 3State Outputs B0B7 Side B 3State Inputs or 3State Outputs 1 2 3 4 567 9 11 8 10 12 ORDERING INFORMATION V T/R A0 A1 A2 A3 A4 A5 A6 A7 GND GND See detailed ordering and shipping information in the package CCA dimensions section on page 5 of this data sheet.
