M74HC238 3 TO 8 LINE DECODER s HIGH SPEED: tPD = 15ns (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 M74HC238B1R s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 238 SOP M74HC238M1R M74HC238RM13TR TSSOP M74HC238TTR DESCRIPTIONThe M74HC238 is an high speed CMOS 3 TO 8 inhibited and all the 8 outputs go low. Three LINE DECODER fabricated with silicon gate enable inputs are provided to ease cascade C2MOS technology. connection and application of this address If the device is enabled, 3 binary select inputs (A, decoder in memory systems. B and C) determine which one of outputs will go All inputs are equipped with protection circuits high. When enable input G1 is held "Low" or either against static discharge and transient excess G2A or G2B is held "High" decoding function is voltage.
