The 74F193 is a 4-bit synchronous up/down counter in the binary mode. It provides synchronous reversible counting, asynchronous parallel load capability, asynchronous reset (clear) and cascadable without external logic.
The document is a datasheet for the Philips 74F193, described as a 4-bit synchronous up/down binary counter. It features separate up and down clock inputs (CPu and CPd) to simplify operation and includes asynchronous parallel load and reset capabilities.
The text provides detailed technical specifications including absolute maximum ratings, recommended operating conditions, DC electrical characteristics, and AC electrical parameters such as propagation delays and setup times. It also includes logic diagrams, state diagrams, timing waveforms, and a function table describing the device's behavior under various input conditions.
| Operating Temperature Range | 0°C to +70°C |

A High level on the Master Reset (MR) input disables parallel load gates, overrides both clock inputs, and sets all Q outputs Low.
The absolute maximum supply voltage rating is +7.0 V.
