TinyLogic Family, Fairchild Semiconductor

Fairchild’s TinyLogic® family consists of a broad spectrum of high speed, low power, CMOS single and dual gate logic functions in a choice of six space saving packages: SOT23-5, SC70 6-lead, US8 8-lead, and MicroPak 6 and 8 terminal leadless packages.

Reduces routing complexity
Allows shorter metal traces to minimise EMI generation
Prevents unnecessary power consumption from unused gates
HS and HST family intended for 5V or very low speed applications
UHS family ideal for high speed, low voltage operation
ULP family ideal for extremely high speed low voltage operation
ULPA family ideal for low power consumption, low voltage operation
