I need to know when the 14 MSB bits from the address bus of a z80 CPU are high. To do so my first idea is to use 4 74LS08 ICs (TTL AND gates) reading those lines but I don't know the maximum amount of current that can be drained from the CPU.
The 74LS08 has a maximum input current is of 0.1mA hence 1.4mA from the z80 but I cannot find the maximum z80 ratings on the zilog datasheet. The z80 datasheet mentions a TTL chip select decoder connected to the address bus but no mention of the IC ratings are given.
so, can I connect 14 TTL inputs to the z80 address bus without overloading the z80 outputs?

74LS08 datasheet
Clarification
One TTL input per address line, not 14 TTL inputs per address line.
