DESCRIPTION

· The HEF4538B is a dual retriggerable-resettable monostable multivibrator.

· It features active LOW and HIGH trigger/retrigger inputs, an active LOW direct reset input, and complementary outputs.

· External timing components (C_EXT and R_EXT) determine the output pulse width, which ranges from 10 μs to infinity.

· The device operates over a V_DD range of 3 V to 15 V and is designed using LOCMOS technology for precise pulse width control.

FEATURES

· Tolerant of slow trigger rise and fall times.

· Wide supply voltage range from 3.0 V to 15.0 V.

· CMOS low power dissipation and high noise immunity.

· Fully static operation with standardized symmetrical output characteristics.

· Complies with JEDEC standard JESD 13-B and offers robust ESD protection.

· Specified for temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C.

APPLICATIONS

· Precision timing circuits.

· Pulse width modulation systems.

· Retriggerable delay circuits.

· Reset and timing control in digital systems.

· Applications requiring accurate and stable pulse generation.
