This datasheet is the HCF4049UB datasheet
The HCF404BUB is a monolithic integrated circuit that functions as an inverting hex buffer/converter, enabling CMOS to DTL/TTL level conversion with a single supply voltage. It is offered in DIP‑16 and SOP‑16 packages and can drive two DTL/TTL loads directly.
The datasheet details absolute maximum ratings, recommended operating conditions, DC specifications, dynamic electrical characteristics, and mechanical dimensions, allowing designers to assess performance across supply voltages from –0.5 V to +22 V.
| Supply Voltage (VDD) | -0.5 V to +22 V |
|---|---|
| Typical Propagation Delay (tPD) at VDD=10 V | 40 ns (typ.) |
| Power Dissipation per Package | 200 mW |
The typical propagation delay is 40 ns when VDD is 10 V.
The device can be operated up to a supply voltage of +22 V.
