MIL-M-38510-13 Microcircuits, Digital, Bipolar, Ttl, Counters Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, TTL, binary and decade counters. Two product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/13G

NOTES:

1. The pulse generator has the following characteristics: PRR ≤ 1 MHz, ZOUT = 50 Ω, duty cycle = 50%.

2. CL includes probe and jig capacitance.

3. All diodes are 1N3064, or equivalent.

4. Count-up and count-down pulse shown are for device type 09 binary counters. Count cycle for the device type 08 decade counter is 1 through 10.

5. Waveforms for outputs QA, QB, and QC are omitted to simplify the drawing.

6. Load circuits on a given output are only required where the specific test given in

table III indicates "OUT" on that output. Load circuits may otherwise be omitted.
