MC10E/100E136 is a 6-bit synchronous, presettable, cascadable universal counter. The device generates a look-ahead-carry output and accepts a look-ahead-carry input. These two features allow for the cacading of multiple E136’s for wider bit width counters that operate at very nearly the same frequency as the stand alone counter.
This document is a technical datasheet for the MC10E136 and MC100E136, which are 6-bit synchronous, presettable, and cascadable universal counters. The devices feature look-ahead-carry input and output capabilities, allowing for the cascading of multiple units to create wider bit-width counters that operate at high frequencies with minimal performance impact. Key features include fully synchronous up and down counting, an asynchronous master reset, and internal input pulldown resistors.
| Count Frequency | 550 MHz |
|---|---|
| Power Supply Voltage (100E) | -4.2 V to -5.46 V |
| Package Type | 28-lead PLCC |
| Input Pulldown Resistors | 75 kΩ |
| Maximum Power Supply Current (100E) | 170 mA |
The MR pin is an asynchronous master reset signal which, when asserted, forces the Q outputs LOW.
The Q outputs need not be terminated; leaving them open is recommended to save power and minimize noise.
The maximum count frequency is 550 MHz.
