MM54HC4040 Datasheet | National Semiconductor

Description The MM54HC4020 MM74HC4020 MM54HC4040 MM74HC4040 are high speed binary ripple carry counters These counters are implemented utilizing advanced silicongate CMOS technology to achieve speed performance similar to LS-TTL logic while retaining the low power and high noise immunity of CMOS The ’HC4020 is a 14 stage counter and the ’HC4040 is a 12stage counter Both devices are incremented on the falling edge (negative transition) of the input clock and all their outputs are reset to a low level by applying a logical high on their reset input These devices are pin equivalent to the CD4020 and CD4040 respectively All inputs are protected from damage due to static discharge by protection diodes to VCC and ground Features Y Y Y Y Y Typical propagation delay 16 ns Wide operating voltage range 2- 6V Low input current 1 m A maximum Low quiescent current 80 m A maximum (74HC Series) Output drive capability 10 LS-TTL loads Connection Diagrams Dual-In-Line Packages ’HC4020 TL F 5216- 1 ’HC4040 TL F 5216 - 3 Order Number MM54HC4020 4040 or MM74HC4020 4040 C1995 National Semiconductor Corporation TL F 5216 RRD-B30M105 Printed in U S A http://..
