Since this is a TTL device, the transistors will be reverse-biased with the supply reversed (power pins are typically in opposite corners, so reverse-installation reverses power). With reverse-bias, there will be almost zero current, therefore the device wont get damaged.
Bulk CMOS devices have parasitic diodes between Vcc and GND, so if the device is inserted backwards (which results in reversed power-supply pins in many cases), they will conduct a lot of current and can get destroyed. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
