MM54HC154 MM74HC154 4-to-16 Line Decoder September 1990 MM54HC154 MM74HC154 4-to-16 Line Decoder General Description This decoder utilizes advanced silicon-gate CMOS technology and is well suited to memory address decoding or data routing applications It possesses high noise immunity and low power consumption of CMOS with speeds similar to low power Schottky TTL circuits The MM54HC154 MM74HC154 have 4 binary select inputs (A B C and D) If the device is enabled these inputs determine which one of the 16 normally high outputs will go low Two active low enables (G1 and G2) are provided to ease cascading of decoders with little or no external logic Each output can drive 10 low power Schottky TTL equivalent loads and is functionally and pin equivalent to the 54LS154 74LS154 All inputs are protected from damage due to static discharge by diodes to VCC and ground Features Y Y Y Y Typical propagation delay 21 ns Power supply quiescent current 80 mA (74HC) Wide power supply voltage range 2

occur at VCC e 5 5V and 4 5V respectively (The VIH value at 5 5V is 3 85V ) The worst case leakage current (IIN ICC and IOZ) occur for CMOS at the higher voltage and so the 6 0V values should be used VIL limits are currently tested at 20% of VCC The above VIL specification (30% of VCC) will be implemented no later than Q1 CY’89 2 AC Electrical Characteristics VCC e 5V Symbol tPHL tPLH Parameter
