DESCRIPTION
:DESCRIPTION
OF OPERATION: 32 (16) BIT BINARY UP COUNTER - LS7061 (LS7063) The 32 (16) bit static ripple through counter increments on the negative edge of the input count pulse. Maximum ripple time is 4µs (2µs) - transition count of 32 (16) ones to 32 (16) zeros. Guaranteed count frequency is DC to 15MHz. See Figure 8A (8B) for Block Diagram. COUNT - LS7061, COUNT A - LS7063 Input count pulses to the 32 (first 16) bit counter may be applied through this input. This input is the most significant bit of the external data byte.
