74LVX163

74LVX163 Low Voltage Synchronous Binary Counter with Synchronous Clear October 1996 Revised March 1999 74LVX163 Low Voltage Synchronous Binary Counter with Synchronous Clear General Description The LVX163 is a synchronous modulo-16 binary counter. This device is synchronously presettable for application in programmable dividers and has two types of Count Enable inputs plus a Terminal Count output for versatility in forming multistage counters. The CLK input is active on the rising edge. Both PE and MR inputs are active on low logic levels. Presetting is synchronous to rising edge of the CLK and the Clear function of the LVX163 is synchronous to the CLK. Two enable inputs (CEP and CET) and Carry Output are provided to enable easy cascading of counters, which facilitates easy implementation of n-bit counters without using external gates. The inputs tolerate voltages up to 7V allowing the interface of 5V systems to 3V systems. Features s Input voltage level translation from 5V to 3V s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise and dynamic threshold performance Ordering Code: Order Number 74LVX163M 74LVX163SJ 74LVX163MTC Package Number M16A M16D MTC16 Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
