TABLE III. Group A inspection for device type 51 - Continued.
11 Terminals not designated may be "HIGH" level logic, "LOW" level logic, or open except as follows: VIC(pos) tests; the VSS terminal shall be open.
VIC(neg) tests; the VDD terminal shall be open.
ISS tests; the output terminals shall be open.
21 The ISS test measurements shall be run in sequence.
31 Apply single clock pulse; VIN = 0 V to VDD.
41 Apply clock pulse; VIN = 0 V dc to VDD until proper output state is achieved.
51 VIH and VIL tests are performed by repeating the truth table test (numbers 79 through 94) using the input and output conditions as follows:

61 The device manufacturer may, at his option, measure IIL and IIH at 25°C for each individual input or measure all inputs together.
71 See 4.4.1c.
81 The truth table test shall be performed in sequence.
91 The truth table tests shall be performed at VIH and VDD ≤ 5 V dc and ; 18 V dc.
L = VSS +0.5 V maximum, and H = VDD -0.50 V dc minimum.
101 The maximum clock frequency (fCL) requirement is considered met if proper output state changes occur with the pulse repetition period set to that given in the limits column.
111 The device manufacturer may perform VIL1VIH tests as functional tests.
