CLOCK OSCILLATORS – Ultra Low Current Logic: HCMOS “H57-32.768K Series” 5x7 mm Wave Form: Square wave MERCURY Since 1973 H57-32.768K offers the benefits of 32.768 KHz precise timing with the frequency stability that tuning fork type oscillators (LPO57) can’t achieve, and miniaturized packaging. If current consumption is not critical, H57-32.768K is an ideal choice of real time clock timing. Temperature compensated versions of H57 (VM57T and M57T-32.768K) offer frequency stability as tight as ±1 ppm. General Specifications TA=+25°C, VDD at specified voltage, CL=15 pF Product Series Frequency Input Voltage (VDD) Output Logic Output Voltage HIGH “1”; VOH Output Voltage LOW “0”; VOL Rise Time / Fall Time Fanout (Drive Capability) Duty Cycle (Symmetry) Start-up Time (Ts) Load Current Consumption Commercial (0°C to +70°C) Temperature code Frequency is ‘C” Stability(1) H57-32.768K. 32.768 KHz. Other frequencies between 19.5 KHz and 75.5 KHz are also available but limited to some standard frequencies. Please contact Mercury for availability. +2.25 V min; +3.6 V max.
