INTEGRATED CIRCUITS 74LV273 Octal D-type flip-flop with reset; positive-edge trigger Product specification Supersedes data of 1997 Apr 07 IC24 Data Handbook 1998 May 29 Philips Semiconductors Product specification 74LV273 Octal D-type flip-flop with reset; positive edge-trigger FEATURES DESCRIPTION • Wide operating voltage: 1.0 to 5.5V • Optimized for Low Voltage applications: 1.0 to 3.6V • Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V • Typical VOLP (output ground bounce) 0.8V @ VCC = 3.3V, The 74LV273 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC/HCT273. The 74LV273 has eight edge-triggered , D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs load and reset (clear) all flip-flops simultaneously. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop. Tamb = 25°C • Typical VOHV (output VOH undershoot) 2V @ VCC = 3.3V, Tamb = 25°C All outputs will be forced LOW independently of clock or data inputs by a LOW voltage level on the MR input. • Ideal buffer for MOS microprocessor or memory • Common clock and master reset • Output capability: standard • ICC category: MSI The device is useful for applications where the true output only is required and the clock and master reset are common to all storage elements.
