Download the 54191 datasheet PDF. This datasheet also covers the 54191-SGS variant, as both devices belong to the same 4 bit synchronous up/down counters family and are provided as variant models within a single manufacturer datasheet.
The M54/74HC190/191 are high speed CMOS 4-BIT SYNCHRONOUS UP/DOWN COUNTERS fabricated in silicon gate C2MOS technology.
They have the same high speed performance of LSTTL combined with true CMOS low power consumption.
