Would you believe octal latches? Sorry about that, Chief.
Since we're at it:
It's not 8 latches: There are 8 D-type flip-flops in a '374.
Latches pass the input with one control level (the output follows the input, no clock involved) and latch their input value with the control at the other level, much like an analog sample and hold. Compare 7475 (quad latch).
The '374 uses a clock to transfer the data at the D-inputs to the complementary outputs.
