74HC123

Description :

The 74HC/HCT123 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT123 are dual retriggerable monostable multivibrators with output pulse width control by three methods. The basic pulse time is programmed by selection of an external resistor (REXT) and capacitor (CEXT). The external resistor and capacitor are normally connected as shown in Fig.6.
Once triggered, the basic output pulse width may be extended by retriggering the gated active
LOW-going edge input (nA) or the active HIGH-going edge input (nB). By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired. Alternatively an output delay can be terminated at any time by a LOW-going edge on input nRD, which also inhibits the triggering.

Features

• DC triggered from active HIGH or active LOW inputs
• Retriggerable for very long pulses up to 100% duty factor
• Direct reset terminates output pulse
• Schmitt-trigger action on all inputs except for the reset input
• Output capability: standard (except for nREXT/CEXT)
• ICCcategory: MSI

OZ9928 datasheet

Description :

OZ9928 is a high performance, cost-effective 2-channel controller designed for large-size Cold Cathode Fluorescent Lamp (CCFL) or External Electrode Fluorescent Lamp (EEFL) Liquid Crystal Display Television (LCD TV) applications.

The controller provides six drive signals and is capable of driving full-bridge and Class-D topologies. The drive outputs are fixed phase when used for single-side or differential drive applications. Multiple OZ9928s can be synchronized to drive numer ous lamps.

OZ9928 provides total system protection for differential drive and single-side drive applications.
