INTEGRATED CIRCUITS 74LV273 Octal D-type flip-flop with reset positive-edge trigger Product specification 1998 May 29 Supersedes data of 1997 Apr 07 IC24 Data Handbook Philips Semiconductors Product specification 74LV273 Octal D-type flip-flop with reset positive edge-trigger FEATURES DESCRIPTION The 74LV273 is a low-voltage Si-gate CMOS device and is pin and Wide operating voltage: 1.0 to 5.5V function compatible with the 74HC/HCT273. Optimized for Low Voltage applications: 1.0 to 3.6V The 74LV273 has eight edge-triggered , D-type flip-flops with Accepts TTL input levels between V = 2.7V and V = 3.6V individual D inputs and Q outputs. The common clock (CP) and CC CC master reset (MR) inputs load and reset (clear) all flip-flops Typical V (output ground bounce) 0.8V V = 3.3V, OLP CC simultaneously. The state of each D input, one set-up time before T = 25C amb the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop. Typical V (output V undershoot) 2V V = 3.3V, OHV OH CC T = 25C amb 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 The device is useful for applications where the true output only is Common clock and master reset required and the clock and master reset are common to all storage Output capability: standard elements.
