74LVT273
Datasheet
General description
The LVT273 is a high-performance BiCMOS product designed for Vcc operation at 3.3V.
This device has eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common buffered Clock (CP) and Master Reset (MR) inputs load and reset (clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D input, one setup time before the Low-to-High clock transition, is transferred to the corresponding flip-flop?s Q output.
All outputs will be forced Low independent of Clock or Data inputs by a Low Voltage level on the MR input. The device is useful for applications where the true output only is required and the CP and MR are common elements.
Features
- Eight edge-triggered D-type flip-flops
- Buffered common clock
- Buffered asynchronous Master Reset
- Output capability: +64mA/-32mA
- TTL input and output switching levels
- Input and output interface capability to systems at 5V supply
- Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
- Power-up reset
- Live insertion/extraction permitted
- No bus current loading when output is tied to 5V bus
- Latchup protection exceeds 500 mA per JEDEC Std 17
- ESD protection exceeds 2000V per Mil Std 883 Method 3015 and 200V per Machine Model.
