Notes to tables:
(1) Screening and characterization of AC delay parameters are conducted at 10 MHz or less.
Operating conditions: V_CC = 5 V ± 10%, TC = -55° C to 125° C for military use.
(2) All array-dependent delays are specified for an XOR pattern. This pattern includes two product terms and two
pure inputs; all other product terms in the macrocell are held low by one EPROM cell. Other patterns may result
in longer delays. Delays for patterns involving only one product term (such as t_PXZ ) are specified for an XOR
pattern in which only one pure input switches at a time.
(3) When the Turbo Bit is not set (non-turbo mode), a non-turbo adder of 30 ns (maximum) is added to this
parameter to determine worst-case timing. Parameters may not be tested in non-turbo mode, but are
guaranteed to the limits specified. Devices operating in non-turbo mode require one input or I/O transition to
guarantee that the device will enter the correct power-up state.
(4) These parameters may not be tested, but are guaranteed to the limits specified in the table under “Absolute
Maximum Ratings” on page 3.
(5) Not tested directly, but guaranteed by testing t_PD.
(6) The f_MAX values represent the highest frequency for pipelined data.
(7) Not tested directly, but derived from t_SU.
(8) Specified with device programmed as a 16-bit counter with no output loading.
