M74HC245 OCTAL BUS TRANSCEIVER WITH 3 STATE OUTPUTS (NON INVERTED) s HIGH SPEED: tPD = 10ns (TYP.) at VCC = 6V s LOW POWER DISSIPATION:ICC = 4µA(MAX.) at TA=25°C s HIGH NOISE IMMUNITY:VNIH = VNIL = 28 % VCC (MIN.) s SYMMETRICAL OUTPUT IMPEDANCE: DIP SOP TSSOP |IOH| = IOL = 6mA (MIN) s BALANCED PROPAGATION DELAYS:tPLH tPHL ORDER CODES s WIDE OPERATING VOLTAGE RANGE: PACKAGE TUBE T & R VCC (OPR) = 2V to 6V DIP M74HC245B1R s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 245 SOP M74HC245M1R M74HC245RM13TR TSSOP M74HC245TTR DESCRIPTIONThe M74HC245 is an advanced high-speed disable the device so that the buses are effectively CMOS OCTAL BUS TRANSCEIVER (3-STATE) isolated. fabricated with silicon gate C2MOS technology. All inputs are equipped with protection circuits This IC is intended for two-way asynchronous against static discharge and transient excess communication between data buses, and the voltage. direction of data transmission is determined by All floating bus terminals during High Z State must DIR input. The enable input G can be used to be held HIGH or LOW. PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/10 M74HC245 INPUT AND OUTPUT EQUIVALENT CIRCUIT
