input latches; inverting 74HC/HCT4515
FEATURES Inverting outputs Output capability: standard ICC category: MSI
GENERAL DESCRIPTIONThe 74HC/HCT4515 are high-speed Si-gate CMOS
devices and are pin compatible with “4515” of the “4000B”
series. They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT4515 are 4-to-16 line
decoders/demultiplexers having four binary weighted
address inputs (A0 to A3) with latches, a latch enable input
(LE), and an active LOW enable input (E). The 16 inverting
outputs (Q0to Q15) are mutually exclusive active LOW.
When LE is HIGH, the selected output is determined by the
data on An. When LE goes LOW, the last data present at are stored in the latches and the outputs remain stable.
WhenE is LOW, the selected output, determined by the
contents of the latch, is LOW. WhenE is HIGH, all outputs
are HIGH. The enable input (E) does not affect the state of
the latch.
When the “4515” is used as a demultiplexer,E is the data
input and A0 to A3 are the address inputs.
QUICK REFERENCE DATAGND= 0 V; Tamb =25 °C; tr =tf= 6 ns
Notes CPD is used to determine the dynamic power dissipation (PD in μW): =CPD × VCC2 × fi +∑ (CL × VCC2 × fo) where:= input frequency in MHz= output frequency in MHz
∑ (CL × VCC2 × fo)= sum of outputs= output load capacitance in pF
VCC= supply voltage in V For HC the condition is VI= GND to VCC
For HCT the condition is VI= GND to VCC − 1.5 V
