TS555 = 2.7 MHz versus Pin connections f(max) NE555(a) = 0.1 MHz). (top view) Timing remains accurate in both monostable and astable mode. *1' && 9 The TS555 provides reduced supply current 7ULJJHU 'LVFKDUJH spikes during output transitions, which enable the 2XWSXW 7KUHVKROG use of lower decoupling capacitors compared to 5HVHW &RQWURO 9ROWDJH those required by bipolar NE555(a). With the high input impedance (1012Ω), timing capacitors can also be minimized. Features • Very low power consumption: – 110 µA typ at VCC = 5 V – 90 µa typ at VCC = 3 V • High maximum astable frequency of 2.7 MHz • Pin-to-pin functionally-compatible with bipolar NE555(a) • Wide voltage range: +2 V to +16 V • Supply current spikes reduced during output transitions • High input impedance: 1012 Ω • Output compatible with TTL, CMOS and logic MOS a.
