SENSE AMPLIFIERS
MAXIMUM RATINGS (TA =25°C UNLESS OTHERWISE NOTED)
MC1441F,L,P(Oto +75°c)
Mc1541F,~(–55 to +125°C)
consisting of adual-channel gated sense am-
pii}ier with separate wideband differential input
amplifiers. Either can be gated on from saturated
logic levels. The sense amplifier features adjust-
able threshold, saturated logic output levels, and
astrobe input that accommodates saturated
logic levels. Designed to detect bipolar signals
from either of two sense lines. Operates with
core memory cycle times less than 0,5 ~s.
.Nominal Threshold —17 mV
.Input Offset Voltage —1.0 mV typical
●Propagation Delay
Input to Gate-Output – 20 ns
Input to Amplifier-Output – 10 ns
Gate Response Time – 15 ns
Strobe Response Time – 15 ns
