74AC273 Datasheet | STMicroelectronics

DESCRIPTION .. protection circuits against static discharge, giving The AC273 is a high-speed CMOS OCTAL them 2KV ESD immunity and transient excess D-TYPE FLIP FLOP WITH CLEAR fabricated voltage. with sub-micron silicon gate and double-layer 2 metal wiring C MOS technology. It is ideal for low power applications mantaining high speed s HIGH SPEED: f MAX = 190 MHz (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 8 µA (MAX.) at TA = 25 o C HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) 50Ω TRANSMISSION LINE DRIVING CAPABILITY SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 m A (MIN) BALANCED PROPAGATION DELAYS: t PLH ≅ t PHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION PATIBLE WITH 74 SERIES 273 IMPROVED LATCH-UP IMMUNITY B M (Plastic Package) (Micro Package) ORDER CODES : 74AC273B 74AC273M PIN CONNECTION AND IEC LOGIC SYMBOLS November 1998 1/10 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1 2, 5, 6, 9, 12, 15, 16, 19 3, 4, 7, 8, 13, 14, 17, 18 11 SYMBOL CLEAR Q0 to Q7 NAME AND FUNCT ION Asyncronous Master Reset (Active LOW) Flip-Flop Outpus D0 to D7 Data Inputs CLOCK Clock Input (LOW-to-HIGH, Edge Triggered) Ground (0V) Positive Supply Voltage 10 20 GND VCC TRUTH TABLE INPUTS CL EAR L H H H X:Don’t Care OUT PUT S CLO CK X Q L L H Qn F UNCTIO N CLEAR D X L H X NO CHANGE LOGIC DIAGRAMS Thislogic diagram has notbe used to esimate propagation delays 2/10 ABSOLUTE MAXIMUM RATINGS Symbol VCC VI VO IIK IOK IO Tstg TL Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Current Storage Temperature Lead Temperature (10 sec) Parameter Value -0.5 to +7 -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 ± 20 ± 20 ± 50 ± 400 -65 to +150 300 Unit V V V m A m A m A m A o o ICC or IGND DC VCC or Ground Current Absolute Maximum Ratings are those values beyond which damage to the device may occur.
