IW4516B Presettable Binary Up/Down Counter is a high-performance counter with high-voltage silicon-gate CMOS.
The document describes the TW4516B/IW4516B Presettable Up/Down Counter, which consists of four synchronously clocked D-type flip-flops connected as counters. The device can be cleared by a high level on the RESET line and preset to any binary number present on the jam inputs via the PRESET ENABLE line.
The datasheet provides detailed electrical characteristics including DC parameters for supply voltages ranging from 3.0V to 18V, AC propagation delays, timing requirements, and maximum ratings such as a storage temperature of -65°C to +150°C.
| Operating Voltage Range | 3.0 to 18 V |
|---|---|
| Operating Temperature | -55° to 125° C |
| Storage Temperature | -65 to +150 °C |
| Maximum DC Supply Voltage | +20 V |
The maximum input current is 1 µA at 18V over the full package-temperature range.
The counter can be cleared by applying a high level to the RESET line.
