74HC5555 Programmable delay timer with oscillator Rev. 4 5 July 2018 Product data sheet 1 General description The 74HC5555 is a precision programmable delay timer which consist of: 24-stage binary counter integrated oscillator (using external timing components) retriggerable/non-retriggerable monostable automatic power-ON reset output control logic oscillator control logic overriding asynchronous master reset (MR). The 74HC5555 inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2 Features and benefits Supply voltage range from 2.0 V to 6.0 V CMOS input levels Positive and negative edge triggered Retriggerable or non-retriggerable Programmable delay: minimum: 100 ns maximum: depends on input frequency and division ratio 24 Divide-by range of 2 to 2 Direct reset terminates output pulse Very low power consumption in triggered start mode 3 oscillator operating modes: RC oscillator Crystal oscillator External oscillator Device is unaffected by variations in temperature and V when using an external CC oscillator Automatic power-ON reset Schmitt trigger action on both trigger inputs Direct drive for a power transistor High precision due to digital timing Complies with JEDEC standard no. 7 A ESD protection: HBM EIA/JESD22-A114A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V Specified from -40 C to +85 C and -40 C to +125 CNexperia 74HC5555 Programmable delay timer with oscillator 3 Applications Motor control Delay circuits Precision timing Domestic appliances 4 Ordering information Table 1.Ordering information Type number Package Temperature range Name Description Version 74HC5555D 40 C to +125 C SO16 plastic small outline package 16 leads SOT109-1 body width 3.9 mm 5 Functional diagram X / Y CTRDIVm T 10 1 0 Y = 0 11 2 12 4 13 8 15 Y = 15 G 2 RX 3 CX + 14 16G17 1 17 6 & CT = 0 4 1 CT = m R 9 5 S 7 V16 I = 0 R 15 R aaa-028555 Figure 1.IEC logic diagram 74HC5555 All information provided in this document is subject to legal disclaimers.
