Along with the low power dissipation and high noise 2 immunity of standads C MOS integrated circuit, it possesses the capability to drive 15 LSTTL loads. These IC’s are intended for two-way asynchronous communication between data buses, and the direction of data trasmission is determined by DIR input. The enable input (G) can be used to disable the device so that the buses are effectively isolated. The HC7245/640/7643/7645 have the same pin PIN CONNECTION (top view) HC7640 HC7643 HC7645/HC7245 configuration and function as the HC245/640/643 and they have a hysteresis characteristics with each input, so HC7245/7640/7643/7645 can be used as a line receiver, etc. All input are equipped with protection circuits against static discharge and transient excess voltage. IT IS PROHIBITED TO APPLY A SIGNAL TO A BUS TERMINAL WHEN IT IS IN OUTPUT MODE AND WHEN A BUS THERMINAL IS FLOATING (HIGH IMPEDANCE STATE), IT IS REQUESTED TO FIX THE INPUT LEVEL BY MEANS OF EXTERNAL PULL DOWN OR PULL UP RESISTOR. HC7245 is electrically and funcutionally the same as the HC7645 January 1994 1/10 M54/M74HC7245/7640/7643/7645 I NPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1 2, 3, 4, 5, 6, 7, 8, 9 18, 17, 16, 15, 14, 13, 12, 11 19 10 20 SYMBOL DIR A1 to A8 B1 to B8 NAME AND FUNCTION Directional Control Data Inputs/Outputs Data Inputs/Outputs G GND VCC Output Enabel Input (Active LOW) Ground (0V) Positive Supply Voltage IEC LOGIC SYMBOLS HC7640 HC7643 HC7645 TRUTH TABLE INPUT G L L H X: ”H” or ”L” Z: High impedance FUNCTION DIR L H X A BUS OUTPUT INPUT Z B BUS INPUT OUTPUT Z HC7640 A=B B=A Z OUTPUT HC7643 A=B B=A Z HC7645/7245 A=B B=A Z 2/10 M54/M74HC7245/ 7640/7643/7645 A BSOLUTE MAXIMUM RATINGS Symbol VCC VI VO IIK IOK IO ICC or IGND PD Tstg TL Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Source Sink Current Per Output Pin DC VCC or Ground Current Power Dissipation Storage Temperature Lead Temperature (10 sec) Parameter Value -0.5 to +7 -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 ± 20 ± 20 ± 35 ± 70 500 (*) -65 to +150 300 Unit V V V mA mA mA mA mW o o C C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
