1. general description the 74hc373; 74hct373 is a high-speed si-gate cmos device and is pin compatible with low-power schottky ttl. it is speci?ed in compliance with jedec standard no. 7a. the 74hc373; 74hct373 is an octal d-type transparent latch featuring separate d-type inputs for each latch and 3-state outputs for bus oriented applications. a latch enable (le) input and an output enable ( oe) input are common to all latches. the 74hc373; hct373 consists of eight d-type transparent latches with 3-state true outputs. when le is high, data at the dn inputs enters the latches. in this condition the latches are transparent, i.e. a latch output will change state each time its corresponding d input changes. when le is low the latches store the information that was present at the d inputs a set-up time preceding the high-to-low transition of le. when oe is low, the contents of the 8 latches are available at the outputs. when oe is high, the outputs go to the high- impedance off-state. operation of the oe input does not affect the state of the latches. the 74hc373; 74hct373 is functionally identical to: ? 74hc533; 74hct533: but inverted outputs ? 74hc563; 74hct563: but inverted outputs and different pin arrangement ? 74hc573; 74hct573: but different pin arrangement 2. features n 3-state non-inverting outputs for bus oriented applications n common 3-state output enable input n functionally identical to the 74hc563; 74hct563, 74hc573; 74hct573 and 74hc533; 74hct533 n esd protection: u hbm eia/jesd22-a114-c exceeds 2 000 v u mm eia/jesd22-a115-a exceeds 200 v n speci?ed from - 40 cto+85 c and from - 40 c to +125 c 74hc373; 74hct373 octal d-type transparent latch; 3-state rev. 03 20 january 2006 product data sheet
