4020B Inventory, Pricing, Datasheets from Authorized Distributors at ECIA. Instant results for 4020B. Description The 74HC138 is a high speed CMOS device. The device accepts a three bit binary weighted address on input pins A0, A1 and A2 and when enabled will produce one active low output with the remaing seven being high. There are two active LOW enable inputs E1 and E2, and one active HIGH enable input E3. CD4020B, CD4024B, and CD4040B are ripple- carry binary counters.
All counter stages are master- slave flip- flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input- pulse line permits.
