SN74LVC14A Hex Schmitt Trigger Inverter

The high-performance silicon-gate CMOS MC74HC157A has the same pin-out as the LS157. The device inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs. The device sends 2 nibbles (A or B) to a port (Y) determined by a select input. Data is presented at the output in non-inverted form. A high on the output enable input sets all four Y outputs low.
