HEF4017BP集成電路（IC）的計數(shù)器除法器規(guī)格書PDF中文資料

General description

The HEF4017B is a 5-stage Johnson decade counter with ten spike-free decoded active HIGH outputs (Q0 to Q9), an active LOW carry output from the most significant flip-flop (Q5-9), active HIGH and active LOW clock inputs (CP0, CP1) and an overriding asynchronous master reset input (MR).

The counter is advanced by either a LOW-to-HIGH transition at CP0 while CP1 is LOW or a HIGH-to-LOW transition at CP1 while CP0 is HIGH (see Table 3).

Features

■ Automatic counter correction

■ Tolerant of slow clock rise and fall times

■ Fully static operation

■ 5 V, 10 V, and 15 V parametric ratings

■ Standardized symmetrical output characteristics

■ Operates across the automotive temperature range ?40 °C to +125 °C

■ Complies with JEDEC standard JESD 13-B

■ ESD protection:

◆ HBM JESD22-A114E exceeds 2000 V

◆ MM JESD22-A115-A exceeds 200 V

Applications

■ Industrial and automotive
