The 74HC/HCT534 is a high-speed Si-gate CMOS device with 3-state inverting outputs for bus oriented applications. It is an 8-bit positive, edge-triggered register with a common 3-state output enable input, output capability of bus driver and ICC category of MSI.
The document is a product specification for the 74HC/HCT534 integrated circuit. It details features such as being high-speed Si-gate CMOS devices compatible with low power Schottky TTL, featuring separate D-type inputs for each flip-flop and common clock and output enable inputs.
The datasheet provides quick reference data including propagation delays, maximum clock frequency, and input capacitance. It includes ordering information for various packages like plastic small outline (SOT163-1) and dual in-line (SOT146-1), along with pin descriptions, logic symbols, functional diagrams, and AC/DC characteristic tables.
| Propagation delay (CP to Qn) | 12 ns (typical, HC) |
|---|---|
| Maximum clock frequency | 61 MHz (HC), 40 MHz (HCT) |
| Input capacitance | 3.5 pF |
| Power dissipation capacitance per flip-flop | 19 pF |
| Operating temperature range (HC) | -40 to +85 °C |
It contains 8 flip-flops, making it an octal D-type flip-flop.
When OE is HIGH, the outputs go to the high impedance OFF-state.
