74HC237
FEATURES
- bines 3-to-8 decoder with 3-bit latch
- Multiple input enable for easy expansion or independent controls
- Active HIGH mutually exclusive outputs
- Output capability: standard
- ICC category: MSI GENERAL DESCRIPTION
The 74HC/HCT237 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. 7A.
74HC/HCT237
The 74HC/HCT237 are 3-to-8 line decoder/demultiplexers with latches at the three address inputs (An). The “237” essentially bines the 3-to-8 decoder function with a 3-bit storage latch. When the latch is enabled (LE = LOW), the “237” acts as a 3-to-8 active LOW decoder. When the latch enable (LE) goes from LOW-to-HIGH, the last data present at the inputs before this transition, is stored in the latches. Further address changes are ignored as long as LE remains HIGH. The output enable input (E1 and E2) controls the state of the outputs independent of the address inputs or latch...
