JAJSDN3F December 2016 – April 2024 TDP158
PRODUCTION DATA
The TDP158/I implement a two stage standby power process.
Stage 1: If there is no signal on the clock line, then the maximum IVCC ≅ 7mA and maximum IVDD ≅ 7mA.
Stage 2: If a signal (like a noise or clock signal) is on the clock line, then the TDP158 investigates the clock line for 3 μs to 5 μs and detects if a signal is present.
In stage 2; maximum IVCC ≅ 7mA and maximum IVDD ≅ 27mA.
