74LVT273 3.3 V octal D-type ip-op Rev. 03 10 September 2008 Product data sheet 1. General description The 74LVT273 is a high-performance BiCMOS product designed for V operation at CC 3.3 V. This device has eight edge-triggered D-type ip-ops with individual D inputs and Q outputs. The common buffered Clock (CP) and Master Reset (MR) inputs load and reset (clear) all ip-ops 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 ip-ops Q output. All outputs will be forced LOW independent of the clock or data inputs by a LOW voltage level on the MR input. The device is useful for applications where only the true output is required and the CP and MR are common elements. 2.
