TSSOP14 SO-14 Description The 74LCX07 device is a low-voltage CMOS open drain hex buffer manufactured with submicron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low-power and high-speed 3.3 V applications and can be interfaced to a 5 V signal environment for inputs. The internal circuit is composed of 2 stages including a buffer output, which provides high noise immunity and stable output. It has the same speed performance at 3.3 V as the 5 V AC/ACT family, combined with lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.
