- Pin-to-pin functionally-patible 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 patible with TTL, CMOS and logic MOS
- production data
Description
The TS555 is a single CMOS timer with very low consumption:

V versus and high frequency:
(f(fmf(maxa)x N.) TES55555(5a)==20.7.1MMHHzzv).ersus
Timing remains accurate in both monostable and astable mode.
The TS555 provides reduced supply current spikes during output transitions, which enable the use of lower decoupling capacitors pared to those required by bipolar NE555(a).
With the high input impedance (1012Ω), timing capacitors can also be minimized. a. Terminated product
