M74HC155 DUAL 2 TO 4 LINE DECODER 3 TO 8 LINE DECODER s HIGH SPEED: tPD = 13ns (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 = 4mA (MIN) s BALANCED PROPAGATION DELAYS:tPLH tPHL ORDER CODES s WIDE OPERATING VOLTAGE RANGE: PACKAGE TUBE T & R VCC (OPR) = 2V to 6V DIP M74HC155B1R s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 155 SOP M74HC155M1R M74HC155RM13TR TSSOP M74HC155TTR DESCRIPTIONThe M74HC155 is an high speed CMOS QUAD output pins of each sections. A 1 to 8 line 2-INPUT NAND GATE fabricated with silicon gate demultiplexer can also easily built up by providing C2MOS technology. a data signal to both 1C and 2C inputs; the output It features dual 1 to 4 line demultiplexers with order from the msb is 1Y3, 1Y2, 1Y1, 1Y0, 2Y3, individual strobe inputs (1G and 2G), individual 2Y2, 2Y1, 2Y0. This device can be used as a 2 to data inputs (1C and 2C) and common binary 4 line decoder or a 3 to 8 line decoder when 1C is address inputs (A and B). held high and 2C is held low. When both decoders are enabled by the strobes, All inputs are equipped with protection circuits the inverted output of 1C data and non-inverted against static discharge and transient excess output of 2C data will be brought to the select voltage.
