74AC163 SYNCHRONOUS PRESETTABLE 4-BIT COUNTER s HIGH SPEED: fMAX = 200MHz (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 8µA(MAX.) at TA=25°C s HIGH NOISE IMMUNITY:VNIH = VNIL = 28 % VCC (MIN.) s 50 TRANSMISSION LINE DRIVING DIP SOP TSSOP CAPABILITY s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 24mA (MIN) ORDER CODES s BALANCED PROPAGATION DELAYS: PACKAGE TUBE T & R tPLH tPHL DIP 74AC163B s OPERATING VOLTAGE RANGE:V SOP 74AC163M 74AC163MTR CC (OPR) = 2V to 6V TSSOP 74AC163TTR s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 163 s IMPROVED LATCH-UP IMMUNITY mode of operation as shown in the Truth Table. ALOW signal on CLEAR overrides counting and DESCRIPTION parallel loading and sets all outputs on LOW state The 74AC163 is an advanced high-speed CMOS on the next rising edge of CLOCK. A LOW signal SYNCRONOUS PRESETTABLE COUNTER on LOAD overrides counting and allows fabricated with sub-micron silicon gate and information on Parallel Data inputs to be loaded double-layer metal wiring C2MOS tecnology. It is a into the flip-flop on the next rising edge of CLOCK. 4 bit binary counter with Synchronous Clear. With LOAD and CLEAR HIGH, PE and TE permit The circuit have four fundamental modes of counting when both are HIGH. Conversely, a operation, in order of preference: synchronous
