leading zero blanking

[Atul Patil]

dear friends,
I want suggestions and diagram thereoffor above subject for i. counter with 4510 and 4511 ic's and ii. timer with 74C926 ic.

 

[Sebi]

Very difficult (need lot of gates) if the IC haven't RBI and RBO pins.
The datasheet of C926 not indicate this function - if i remember well - no zero blanking.

Sebi is right - possible, but difficult with 4511, due to no RBO. Better to use 74LS47/74LS48/74LS49 if your circuit is TTL compatible.
